Hi,

Every day at same time, I can read PHP fatal error, concerned with 2 plugins:

BBPress for a forum with very few articles and comments,

WP-Optimize, for page cache and image compression.

No idea where it comes from. No cron at that time….

Every thing is up to date: WP6.9.1 PHP 8.3.30, all plugins with automatic update.

Thank in advance for helping

Didier

Hi,

Thanks for contacting us! The PHP Fatal error appears to be coming from the bbpress plugin in the function called get_query_var() so I would recommend reaching out to them and letting them know if you haven’t yet.

The PHP Notice does appear to be coming from WP-Optimize, however looking at the code we have some extra fallbacks in place to determine if we’re on the search page in case the is_search() function doesn’t work properly.

I’ll still bring this up with our development team to see if we need to make any adjustments to this in a future release.

Thank you!

Now BBPress and Extendify are disactivated and this is the only php-errors taking place every day at same time:

Hi,

Thanks for the update! Thankfully those are PHP notices and not fatal errors like we had seen when bbpress was enabled, but I will report this to development to see if we can improve this functionality in a future update!

Hi,

When the PHP Notices show up again in the log would it be possible to send us the full stack trace? I haven’t been able to reproduce the issue on my test sites so having the full trace from your site will help in our investigation.

Thank you!

Hi,

This is all log from [01-Mar-2026].

No more PHP warning, as BBPress is disactivated and Extendify disinstalled.

Concerning Ionos-essentials I’ve seen an update, which can explain the fact there is no more warning.

Hi,

Thanks so much for providing the log. Unfortunately since it’s a PHP Notice it’s not showing the full stack trace like we had seen with the PHP Fatal Error. In order to validate that it’s WP-Optimize causing the problem, would it be possible to temporarily deactivate our plugin and see if the notices appear at the expected times?

Thank you!
