It seems to me that some other plugin that consumes a lot of memory is to blame. Try disabling other plugins that display something on the post list page * [janslupski](https://wordpress.org/support/users/janslupski/) * (@janslupski) * [5 years, 5 months ago](https://wordpress.org/support/topic/too-much-memory/#post-13808806) * So I’m the second one. I see that problem after upgrade from 3.4.1 to 3.7.6. * If I disable auto-post-thumbnail – no more “memory exhausted error”. If I revert to 3.4.1 – no more “memory exhausted error”. * Will try to figure out at which version it has started. * [janslupski](https://wordpress.org/support/users/janslupski/) * (@janslupski) * [5 years, 5 months ago](https://wordpress.org/support/topic/too-much-memory/#post-13808916) * rev 2154675 from SVN works, rev 2168173 does not From the comments this is change that happened between 3.5.1 & 3.6.0 * Ah, and error occurs at [https://…/wp-admin/edit.php](https://…/wp-admin/edit.php)( maybe other pages too). * hth - This reply was modified 5 years, 5 months ago by [janslupski](https://wordpress.org/support/users/janslupski/). * Thread Starter [WWDay3](https://wordpress.org/support/users/wwday3/) * (@wwday3) * [5 years, 5 months ago](https://wordpress.org/support/topic/too-much-memory/#post-13809081) * By the way, [@webtemyk](https://wordpress.org/support/users/webtemyk/), after the original response 2 months ago, I tried what you suggested and disabled every other plugin on the site, and still got the error. I had no time to pursue the issue further, so I removed your plugin and found another plugin I could work with. I forgot to report the results back here (sorry about that). * [janslupski](https://wordpress.org/support/users/janslupski/) * (@janslupski) * [5 years, 5 months ago](https://wordpress.org/support/topic/too-much-memory/#post-13809265) * [@wwday3](https://wordpress.org/support/users/wwday3/) do you operate on a large database? Since it seems not to be that common issue I wonder what could be additional( non-typical) factor involved… * (My WordPress has ~20K posts and database dump is ~1GiB) * Thread Starter [WWDay3](https://wordpress.org/support/users/wwday3/) * (@wwday3) * [5 years, 5 months ago](https://wordpress.org/support/topic/too-much-memory/#post-13809833) * I would say the site where I had the plugin installed is not larger than yours, perhaps a bit smaller. * The issue presented itself when I updated the plugin from the repository. Before the update, no problem. As soon as I updated, the error occurred. I manually moved the plugin to a “plugins2” directory, the error went away, I submitted the ticket, and looked for a replacement. * Later, I deleted the plugins2 directory, so I can’t even check now what version it was. * Sorry I’m not more help. * [Temyk](https://wordpress.org/support/users/webtemyk/) * (@webtemyk) * [5 years, 5 months ago](https://wordpress.org/support/topic/too-much-memory/#post-13815664) * Hello, [@janslupski](https://wordpress.org/support/users/janslupski/) * can you send me the full text of the error? * [janslupski](https://wordpress.org/support/users/janslupski/) * (@janslupski) * [5 years, 5 months ago](https://wordpress.org/support/topic/too-much-memory/#post-13818312) * This is the exact error message in the apache2 log file (although I’m not sure if it is helpful, as it does not point what exactly exhausted the memory): * ``` [Fri Dec 18 16:54:25.293026 2020] [proxy_fcgi:error] [pid 9348:tid 140635919070976] [client xxxxxxxxxxxxxxxxxx] AH01071: Got error 'PHP message: PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 20480 bytes) in /[xxx]/wp-includes/wp-db.php on line 1972\nPHP message: PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 73728 bytes) in /[xxx]/wp-includes/functions.php on line 4212\n' [Fri Dec 18 16:54:25.293083 2020] [proxy_fcgi:error] [pid 9348:tid 140635919070976] [client xxxxxxxxxxxxxxxxxx] AH01071: Got error 'PHP message: PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0\n' ``` Viewing 8 replies - 1 through 8 (of 8 total) The topic ‘Too much memory’ is closed to new replies. * ![](https://ps.w.org/auto-post-thumbnail/assets/icon-256x256.gif?rev=3469511) * [Auto Featured Image (Auto Post Thumbnail)](https://wordpress.org/plugins/auto-post-thumbnail/) * [Frequently Asked Questions](https://wordpress.org/plugins/auto-post-thumbnail/#faq) * [Support Threads](https://wordpress.org/support/plugin/auto-post-thumbnail/) * [Active Topics](https://wordpress.org/support/plugin/auto-post-thumbnail/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/auto-post-thumbnail/unresolved/) * [Reviews](https://wordpress.org/support/plugin/auto-post-thumbnail/reviews/) ## Tags * [memory allocation](https://wordpress.org/support/topic-tag/memory-allocation/) * 8 replies * 3 participants * Last reply from: [janslupski](https://wordpress.org/support/users/janslupski/) * Last activity: [5 years, 5 months ago](https://wordpress.org/support/topic/too-much-memory/#post-13818312) * Status: not resolved
