• 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.

Issue Plesk 12.5 - Changing PHP version changes app pool

(opened a ticket on this but figured others may encounter the same issue - took me a while to track down what was going on)

I am currently encountering an annoying issue in Plesk 12.5 (latest patch level) running on Windows 2012 R2. I have multiple PHP versions installed (5.x and 7.x). I also have two .NET Framework versions installed (2.x and 4.x) which means Plesk created two App Pools -- plesk(default)(2.0)(pool) and plesk(default)(4.0)(pool). All of my subscriptions default to .NET 4.x. In any case, when I change between PHP versions (e.g. move from PHP 5.6 to 7.0.15) in a subscription, the .NET app pool changes from 4.x to 3.x. While normally this would not be a big deal, it is causing a problem because of the opcache bug on Windows that was reported here (by one of the Plesk devs):

https://bugs.php.net/bug.php?id=72645

So, when the app pool is changed, I start having problems.

Is there a way to specify in the Plesk config someplace what app pool a specific PHP version should use?
