last update of qtranslate-xt creates a fatal error

[Markus]

The last update of qtranslate-xt unfortunately creates a fatal error and you couldn't get into the system. It was some work to restore this.

Last qtranslate-xt update: https://github.com/qtranslate/qtranslate-xt/releases/tag/3.15.1

qtranslate-xt is not my plugin

would be great to see the whole error message not just this small part

for me it works maybe u need to update php to version 8.x in your webhost control panel
