Hello @schngl,
Would it be possible for you to enable Debugging on your site and trigger the issue once more; and share the error message here so that we may look into it?
You can easily enable debugging by activating a plugin such as WP Debugging, but you can also do this manually in your wp-config.php file (instructions here).
Let me know! Kind regards, Jarno

This is there error i get:
PHP Fatal error: mysqli_fetch_object(): Cannot use output buffering in output buffering display handlers in …/wp-includes/class-wpdb.php on line 2320
Hi @schngl,
Could you check if this issue persists when you have Complianz as the only activated plugin, and a default WP theme such as one of the “Twenty Twenty-” themes enabled?
If a plugin or theme is not properly handling output buffering (e.g., not closing it after opening it with ob_start()), this could lead to unexpected behavior.
Kind regards, Jarno

I have checke it with the WP 2024 Theme and Complianz as the only activated plugin – unfortunately the same issue / error.
Hi @schngl,
Strange. It seems that I am unable to replicate this behavior on my end. I’ve did some further searching about the error and it looks like this could also occur when your environment is running out of memory.
Could you check the memory limit of this site, and whether the debug.log file (typically located in your /wp-content/ folder) might contain any other related errors, aside of the one that you already shared?
Kind regards, Jarno

Thanks Jarno!
i have checked the debug file – there is no other error for this case – just the “output buffering” error.
I am using the Complianz Plugin on many other WP-Sites with no issue.
The PHP memory_limit is set to: 740M – this should be enough, right?!
best regards
Hi @schngl,
Yes, that should be more than enough. Some things to check, as I can imagine that they are possibly related:
– Are you using any Complianz shortcodes on the site that experiences the issue? Does it still occur without those shortcodes being used?
– Are you using the Gutenberg editor on this site? If so, could you try if it still occurs with the Classic Editor enabled instead?
But as you mentioned that this behavior doesn’t occur on your other sites with Complianz: is the site experiencing this issue hosted on a different server, with another hosting provider for example?
Perhaps it’s some server configuration that might be related. If the above steps don’t yield any further leads, I would recommend contacting the Hosting Provider to get their opinion on the error and it’s potential causes.
Kind regards, Jarno
