HTTP 500 on Backend

    Hi,

    Today when I tried to login to one of my site’s backends, I received a persistent HTTP 500 error. Frontend worked fine.

    I contacted my host to find out the issue. They told me that updraftplus was causing the issue. When the support deactivated the plugin, the backend became available once more.

    Are there any ongoing issues with the plugin that would be causing this issue?

    I am hesitant to reactivate until I know more. I don’t want to have to contact my site host to regain access to the backend, if I lose access when I reactivate again.

    Hi,

    What was the error logged in the PHP error log?

    The most likely cause, if it was across the whole backend, is that your website is running very close to the hosting company’s allowed memory limit, and that activating one more plugin tipped it over that limit.

    The last error in the log was the following.

    [30-May-2018 20:02:40 UTC] PHP Fatal error: Out of memory (allocated 96993280) (tried to allocate 12288 bytes) in /home2/talschne/public_html/simplydoit.net/wp-content/plugins/js_composer/include/params/params_preset/params_preset.php on line 39

    Would this match your suspicions that the cause was memory limit?

    I do think that my boss added a plugin, or a few, to the site recently.

    But, would this happen to an existing plugin? We’ve had updraftplus active for a while.

    My apologies. I don’t know fully about all of the technical details with this area.

    Thanks for taking the time to reply. Much appreciated. ??

    Hi Kenny,

    Yes, as the error message says, you have an out-of-memory problem. Which plugin appears in the error message is to some extent random; it depends on the order in which WP chooses to load plugins, and what exact operations need to be performed by those plugins at a particular time, on a particular page-load. Here’s how to increase your WP memory limit: https://updraftplus.com/faqs/deal-fatal-error-allowed-memory-size-errors/
