   This Worked for me.

   /**This is a test for memory*/
   define(‘WP_MEMORY_LIMIT’, ’64M’);

   Thank you for this wonderful share.

   Should the memory limit ever be higher than 64M? Most WP sites i’ve worked on the average page load never exceeds 40-5megs. The reason I ask, is I read that the WP_MEMORY_LIMIT defines the amount of memory Wordpress can use per Apache thread. Which means that multiple threads will use more and more, and eventually swap to disk which is never good.

   Anybody an expert and can answer this?

   It seems like WordPress is either unable to create wp-config.php file or the file gets deleted after the install. Use ftp to make sure that there is a wp-config.php file present on your site. If not then try creating one by renaming the wp-config-sample.php file to wp-config.php file. You will need to manually edit the file and provide your database information.

   • WPBeginner Support

     wp-config.php file is usually located in the root folder of your website and can be accessed using FTP client or cPanel file manager.

         don’t double click it. Either right click and select EDIT or highlight it and look for an EDIT button somewhere (maybe at the top if it’s Godaddy). Good Luck!

   I opened the wp-config.php file from my ftp directory.
   I was not sure how to completely enter the adjustment – I didn’t know basic coding for php, so I just copied the basic precursors shown for each entry and added as follows:

   /**This is a test for memory*/
   define(‘WP_MEMORY_LIMIT’, ’64M’);

   It worked!

    Hi,

    I’ve tried to increase the limit to 64mb, and I got this warning until 5 times:

    ‘WARNING: Job restart due to inactivity for more than 5 minutes.’

    The database backup is stopped until 60s%, and the result is below when it tried to upload to Dropbox:

    ‘ERROR: Uploaded file size and local file size don’t match.’

    What’s wrong with it? I’m using Bluehost.

    Thanks!

    PS: I’m not a technical person, so give explanation in details

    Thank you so much!!!!
    I’m in the middle of a launch and all of a sudden I couldn’t update or create any web pages on the whole site because of a 500 Internal Server Error. (And of course this happened as soon as I discovered the Home page had a big problem.)

    Could get no help from support, am not a web developer.

    Yet I was STILL able to follow your instructions and Hallelujah! Miracle of Miracles! Everything works now.

    All this work driving traffic, getting new people to the site – almost wasted due to server error – but Disaster Averted! you saved the day.

    My sincerest gratitude.

    Again, can’t thank you enough.

    On line 36/37 of wordpress, wp-config.php you must type:

    /** Memory Limit */
    define(‘WP_MEMORY_LIMIT’, ’64M’);

    For me this problem is solve thi way. You can change 64M with what value you want.

    Répondre

    • Adam Singer

      This comment is sooo key!

      You have to add define( ‘WP_MEMORY_LIMIT’, ’64M’ ); just before the unique key and salts are defined, otherwise the change doesn’t take effect. Thanks!!!

      • omniafausta

        yesssss thanks, I was wondering why it didn’t work for me. It was because so far no one told me WHERE in the wp-config i had to add this line. THANKS!!!

    • Rosie Taylor

      Thank you for clarifying this step. Now I know why it never just changing the other line for the value didn’t work before. This saved me big time for a client tonight!

    Hello,
    Today I had a problem with wordpress: after I logged appeared « white screen of death ». We went into cpanel and inserted « define (‘WP_MEMORY_LIMIT’, ’64M ‘)’ in wp-config.php and everything went very well.
    Thanks a lot WPBeginner.

    Thanks a lot, i work very hard with every method i found on internet, but i filled , my problem occur during word-press installation i pasted this code in mid and increase its value to 128 mb , now its works fine, thanks a lot again.

22. Jeff Danforth

    My host provides 64MB, and wants a hefty kicker to increase the php memory limit – so I’m inclined to be « green » and reduce my memory use.

    HOW might I determine what plugins or other things to remove to stay under 64MB
    A) php memory consumption, e.g. which plugins are being greedy
    B) have I got a memory leak issue, e.g. any plugins being nasty

    Thank you for this forum, by the way – I am truly a beginner, but excited about WP (grrr, if I can make it jump its hoops right)

    Didn’t work for me, but I’m not sure what it means to be « inside the main php tag ». I opened the file in Dreamweaver and did a search. The word « main » doesn’t appear anywhere on the page. So I put the code in line 2, just after the « <php". Tried it at 64 and 128. Thanks.

    Répondre

    • Editorial Staff

      The main php tag means just insert it like you did. Sometimes this doesn’t work in which case you have to ask your host.

    But 64M was already default for me and of course it wasn’t sufficient so I changed it to 96M and I think u should mention this as well.

    Nice but nothing works – use rackspace cloud – tried 32 – 64 – 128 – 256- 512 – 1024Mb MU site i can’t go more up and only in admin i can’t get access after a plugin from wpmudev so guess i have to delete that and try something pro.

      3define( ‘WP_DEBUG’, true);I found in a post next to this one and was getting an error by using define(‘WP_MEMORY_LIMIT’, ‘128M’); on the last line of my php-config file. Thanks to this comment I placed it right below <?php tag at the top and now the error report is no longer I just hope my site doesn't keep crashing on every new plugin install, going to check that now. Thanks to all you geeks out there!

      Répondre

34. PatrickTyrus

    this was a great help, but as you noted it could easily be a plugin, or as someone mentioned it could be a memory leak.

    And as others have pointed out, there are memory settings for a reason, some hosts will cut your services if you try to circumvent them.

    Is there a way to check on what’s eating memory?

    I’ll be searching, but this is something that should be listed under related posts, or as a note and link at the end regarding one of the « numerous solutions for it ». Going for the « simplest one » might get you through the day, but is may not be a good long term solution as it may cover up the real problem and delay the inevitable.

      Worked for me!! I changed my site language to Spanish and I guess that used up the memory. Added the simple line recommended in the post and voilá!! Back in my admin mode. The really helpful part was « Don’t panic! » because my anxiety level was rising fast.
      Thanks ever so much.

    I ended up having to switch hosting companies because I couldn’t get my current one to increase the memory from 32MB to, well, anything more. Pretty sad. Took a bit of hassle to transfer three Wordpress sites (and multiple other sites), but it was worth it. My current host offers 128MB and my sites are working SO much better. I can actually add plug-ins.

39. Richard

    Hello
    I tried the fix by adding the line immediately after the opening >php tag (line 1)
    define(‘WP_MEMORY_LIMIT’, ’64M’);

    It did not work for me BUT
    I placed the line with comments for my own use on (as it happens) line 22 and it worked.

    I am testing this procedure on a test WP site using Twentyten 1.2 Theme

    /home/par*****/public_html/wp-config.php

    Line 22 /** WP memory limit Note it does not work when placed immediately after line 1 */
    define(‘WP_MEMORY_LIMIT’, ’64M’);

    This trick doesn’t work for me ever since WP 3.

    what I found worked was to create a PHP.INI file in the wp-admin folder with the line:

    memory_limit = 128M

    (or whatever you want to make it)

      Sounds like a host issue rather than WP 3.0 issue. We still have this trick working on our clients.

      On some hosts, this trick won’t work. So you have to ask (beg) them to increase the PHP Memory Limit. OR get rid of the plugin which is causing it.

    Great article. A brand new plugin that may soon find its way on to this list is Cobalt WP Boost.

    Check it out here:
    http://frugaltheme.com/about/cobalt-wp-boost-plugin/

    It allows blog owners to raise their WordPress Memory Limits with a couple of mouse clicks, as well as showing at-a-glance memory usage information. WordPress keeps its internal memory limit at 32MB, which is fine for a small-time blog; but if you’re trying to add any robust plugins for social networking or ecommerce applications, 32M will not suffice. This problem can only be expected to worsen with the release of 3.0 which, judging from the beta release, will consume a lot more memory itself without upping the 32MB limit.

    • Chad McCullough

      I just downloaded the plug-in and I’ll give it a try on my test site. Thanks.

      Répondre

46. W^L+

    Just remember that if the problem is a memory leak (either in PHP itself or in some library that is used by a plugin), this will merely delay the occurence.

    Before you change the memory limits, you should ensure that you’re using the most up-to-date versions of any plugins. Be sure you are running the newest version of WP. If your host offers multiple versions of PHP, be sure you’re using version 5.

    Your hosting service may have preset limits on memory usage. If your editing causes you to exceed those limits, your service may be suspended or canceled without warning.

      Yes, but editing the core files is not the best way. You would have to change that every time you update WordPress. The way we share in this article, will save you time.

        I would much rather not modify core files, if possible. Where would I place the line in the wp-config.php file? I’m not sure where the main php table is.

          Place it right after the table prefix

    I think that this might fix an issue I’ve been having with my site. I just can’t figure out where the main php table is in the wp-confip.php to place the line.
