I am getting this error when trying to create new clients in new installation of 10.4.3 with PHP 8.1:

2023-08-11 18:10:19.099 ** ERROR ** [V10.4.3] on file '/home/.../public_html/.../view/objectDetail.php' at line (10274) 2023-08-11 18:10:19.099 ** ERROR ** [V10.4.3] cause = ob_get_clean(): Failed to discard buffer of zlib output compression (0)

I have tried disabling zlib.output_compression in a php.ini file in the root of the installation (I need it on to run other software on my server in other folders) with no effect. Still can't set anything up. Can anyone guess what's wrong?

Thanks for any help.
