We're seeing a large number of PHP Warnings of the type:
Trying to access array offset on value of type null in /wp-content/plugins/wpforo/themes/2022/layouts/2/post.php on line [various numbers]
Trying to access array offset on value of type null in /stable/wp-content/plugins/wpforo/includes/functions-template.php on line 196
Our host is concerned that they may be leading to issues with stability of the PHP-FPM service, is there anything we can do to reduce these warnings (other than turn off notifications, of course)? We're running the latest version of wpForo.
Hi @upstartdm,
1. Please check the database issues in wpForo > Tools > Database Tables Tab. if you see any issue please click the [Solve Database Problems].
2. Go to wpForo > Settings > Member Rating admin page, scroll down and click [Update Options]
3. Go to wpForo > Overview admin page and click [Delete All Caches] button.
4. Make sure you don't have code snippets hooking wpForo plugin
5. Make sure you don't have outdated wpForo template files in the folder of current active theme.
Thanks, that's a useful reply but unfortunately we've tried all those steps and the warnings are still being logged. Is there anything more we can do to troubleshoot the root cause? We're running PHP version 8.2.12
@robert Thanks, the line numbers of 2022/layouts/2/post.php are:
line 16
line 24
line 30
line 56
(the other lines we see warnings for are /includes/functions-template.php on line 196 and /classes/Actions.php on line 289)
This is not wpForo issue. This issue comes from incorrect data in database. So this issue only exists in your website. We could help you send admin login details to support[at]gvectors.com email address.
@robert Unfortunately our security policy does not allow 3rd party admin access but I can provide (sanitised) data privately if you tell me what you need (or if you can point me to a specific db location I can take a look myself). Thanks.
PS I should add we are also using the User Custom Fields, Private Messages and Polls addons.
Ok, please use one earlier version of wpForo and let us know if you see the same errors. I need to verify this is not 2.2.4 version issue.
@robert OK, happy to test that, how do I downgrade? Just download an older version of the files and overwrite?
@robert Thank you very much indeed, this has completely solved the issue.
@robert BTW the logic of the "solved/unsolved" button at the top of this post appears wrong - it looks like the text needs to be "mark solved" or "mark unsolved" for it to make sense, i.e. to indicate a potential action rather than the current status (currently the status is displayed as "unsolved" within the topic but "solved" in the forum view which seems inconsistent and confusing).
