• 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.

Hi all,

We just upgraded from Plesk Obsidian v18.0.63 to Obsidian v18.0.65 and now we have a problem with a website running PHP 8.1 / FPM - Apache with Symfony and redis.
Everything worked until the updated Plesk msie. We now have this error:

AH01071: Got error 'PHP message: PHP Fatal error: Declaration of Symfony\\Component\\Cache\\Traits\\Redis6Proxy::hSet($key, $member, $value): Redis|int|false must be compatible with Redis::hSet(string $key, mixed ...$fields_and_vals): Redis|int|false in /var/www/vhosts/mydomain.com/httpdocs/releases/111/vendor/symfony/cache/Traits/Redis6Proxy.php on line 519', referer: https://www.mydomain.com/

The website is crashed! Error 500.

The problem persists when regenerating the cache. Which Plesk update caused this and how do I resolve it? Thanks for your help.
