PHP update breaks site through control panel

  • I encountered the following problem when logging into my control panel for my hosting company Crazy Domains, to update the PHP version and to increase settings on the server for settings such as upload_max_filesize, post_max_size, max_input_vars, etc.

    As soon as I did so the site broke and I received a 500 error.

    I rang Crazy Domains and the fix was to go to the File Manager and increase settings via the php.ini file.

    This was their response as to why the problem occurred.

    The update earlier will not sync and it is something to do with the system update with WordPress for some reason it won’t sync until we edited the php.ini folder under public_html.

    Switching the PHP version will also affect the current setup and obviously not carried over to the new PHP version.

    This has been forwarded to our backend support and confirmed that this is not an issue from our control panel but some update from WordPress system update.

    Am I understanding correctly, that it is a WordPress coding issue?

    That is correct.

    Has anyone else experienced this issue?

  • @wotnow I’m not intimately familiar with your hosting environment but from what you have described these are the conclusions I would draw:

    1. Changing your php version isn’t always a simple process.
    2. Possible causes of the 500 server error:
    3. php.ini in your root directory conflicts with the new version of php.
    4. plugin or theme conflict with php version

    I would start by deactivating all plugins and changing your theme to the default Twenty Twenty-Two and then change your php version. If you still get the 500 error this would indicate that the initial problem is in your root directory php.ini and your hosting company would need to help you resolve that conflict, which is relatively easy to do if you understand how php.ini needs to be associated to the version of php you are using.

    If you are able to upgrade your php version and not getting the 500 error, then the conflict is in a theme or plugin. Start by ensuring that your theme and plugin have the most recent updates. Then activate them one at a time starting with your theme and then proceeding through your plugins. After activating each be sure to check if you are getting the 500 error. When you see the 500 error the plugin or theme that you just activated is the culprit (or one of the culprits).

    When you find the plugin or theme that is causing the error report it to the developer and most developers will fix the issue relatively quickly. Until it is fixed, just stop using that particular theme or plugin – if necessary you can probably find a replacement that provides the same functionality in the plugins or themes here on WordPress.

    Good luck and keep us posted on your progress.
