Title: Fatal error: Allowed memory size … Last modified: August 22, 2016 --- # Fatal error: Allowed memory size … * [ChristiMc](https://wordpress.org/support/users/christimc/) * (@christimc) * [11 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-71/) * I have just updated this security plugin on my site and now my events calendar is throwing this error: * **Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 6994 bytes) in /home/xxxxxx/public_html/wp-content/plugins/the-events-calendar/ views/month/single-event.php on line 186″** * I’ve isolated the problem to be this security plugin.

Here’s the page where you can see it occurring: [http://www.theartistsgallery.com/events/category/member-shows/](http://www.theartistsgallery.com/events/category/member-shows/) * [dwinden](https://wordpress.org/support/users/dwinden/) * (@dwinden) * [11 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-71/#post-5904808) * Hmmm … it seems to be working just fine all the way here in Holland using either Mozilla Firefox 36.0.1 or MS Internet Explorer 11.0 from a Windows 7 SP1 client. * Are you still having the memory error on that page ? * Anyway, login to the WP Dashboard and make sure that the “Enable Scheduled Database Backups” checkbox is disabled in the Database Backups section of the iTSec plugin Settings page. * Even though Scheduled Backups are scheduled they are kicked off (once the next scheduled date\time is passed) by users just visiting the website. Might have had some incidental effect … though it doesn’t explain why the issue started after updating the iTSec plugin. But iTSec plugin Scheduled Backups are known to cause memory issues under certain conditions … * Do you remember from what version the iTSec plugin update took place ? * It seems the PHP memory_limit on your server is set to 32 MB. As 32 < 40 WordPress will set the frontend PHP memory_limit to 40 MB. * Should the memory error frequently reoccur then you could try and increase available PHP memory for the frontend by adding the following line to the wp-config.php file: * > define(‘WP_MEMORY_LIMIT’, ’64M’); * Basically increase it to any value > 40 MB. * dwinden * Thread Starter [ChristiMc](https://wordpress.org/support/users/christimc/) * (@christimc) * [11 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-71/#post-5904814) * Interesting. It doesn’t happen in IE11 or Firefox’s 35.0.1. from a Windows 8 client and on Mac OSX. In either client, it fails in Chrome. Unfortunately I don’t remember the version I upgraded from so can’t help there. * Checked the plugin and I don’t have backups enabled. I just added the memory code to the config file. Tried 64M – no change. Tried 128M – no change. * I may have to go to the events plugin support next to see if they have any ideas. * Thank you for the excellent information re: backup and memory problems. I’l keep pursing. * Thread Starter [ChristiMc](https://wordpress.org/support/users/christimc/) * (@christimc) * [11 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-71/#post-5904833) * Ok, I think I have it. I removed the File Change check and that seems to resolve the memory error. Not sure why that feature is so resource intensive but it’s resolved for me at the moment. * Thanks, dwinden, for all your tips and clues. It lead me to the solution! * [dwinden](https://wordpress.org/support/users/dwinden/) * (@dwinden) * [11 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-71/#post-5904841) * Ah, the thought crossed my mind … * Yep, “File Change Detection” is in second place when it comes to iTSec plugin features that may require a lot of memory. And it works just like Scheduled Backups. Kicked off by a user visiting the website after the next scheduled date\ time has passed. * You can actually see how much memory a (successfull\completed) “File Change Detection” scan used by going to the iTSec plugin Logs page and selecting “File Change History” from the Select Filter dropdown list. * I’m a little bit concerned about the fact that the issue also seems to be browser dependant … that is not a good sign. * Still great you were able to pinpoint the problem en therefore find a solution. * Oh there is one question I am really interested in being answered. When you changed the WP_MEMORY_LIMIT in wp-config.php you are saying there was “no change”. So it still produced a memory error in Google Chrome. Did it also still mention the 41943040 bytes memory threshhold ? Or did that threshhold change according to the value set for WP_MEMORY_LIMIT (for 64M it would probably have been something like 67108864 bytes). * Ideally you would like to keep using the “File Change Detection” feature (for security reasons) and raising the WP_MEMORY_LIMIT value should enable you to do that. If the answer to my question is No perhaps you did not set it correctly in wp-config.php.
