Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.
Unless your client runs a separate Roundcube installation on his/her domain, independent of the default Roundcube component used by Plesk, it should not matter. However, as long as PHP 8.3 is installed, the Roundcube component from Plesk will run regardless of the PHP version used for the domain of your customer. Because the Roundcube component from Plesk runs independently from any domain PHP settings/configuration.
If that's not the case for you, provide more details so forum users can make suggestions for troubleshooting any issue you might have.
