Hi @littlepellizza
We saw this “Cannot use output buffering in output buffering display handlers ” error a couple times in the past and in each of the cases the problem happened due to another PHP error, unrelated to our plugin. When bigger PHP errors are happening, they are stopping all PHP codes of your website and they write out an error message instead. Because of this the output buffering starts, so instead of running the rest of the PHP codes which would come, the current website’s state will be displayed. This is why our code couldn’t finish its output buffer related codes.
You should enable the error reporting on your site as we mention here:
then you should repeat the process that triggered the error. This should generate an error log at the path where our documentation mentions ( the root folder of your site ). If you check that, then it might tell you what is the real problem exactly. E.g.:
- in many cases the core problem is a too low memory, so your site reaches the limit and crashes.
- or since you told, this error occurs when you try to upgrade the PHP version, I could also imagine that you have a third party plugin ( or maybe it is your theme ), which is not compatible with PHP 8.3 yet, so it crashes. ( By the way we haven’t received any feedback about conflicts with PHP 8.3 yet and in the past I have already made a couple of tests with PHP 8.3.6 and I haven’t experienced any problems with it, so as far as we know we are compatible with PHP 8.3 )
Either way, if you can see any errors in the error log and you can not figure it out, then please get in touch with us over the ticket system over the link below:
send us the log ( e.g. feel free to upload the log file to a filesharing site like Dropbox and share its link with us in the message ), and we will take a look.
Best regards,
Laszlo.
