[horde] Again a weird problem

[Ruud Baart]

Webmail interface worked great, no problems anymore.

Just until now, suddenly:


PHP message: PHP Fatal error:
PHP message: PHP Fatal error: Cannot redeclare class IMP_Application
(previously declared in 
/home/websites/webmyserver.somewhere.xx/horde/vendor/horde/imp/lib/Application.php:46)
/home/websites/webmyserver.somewhere.xx/horde/vendor/horde/imp/lib/Application.php
while reading response header from upstream, client: 12.34.56.789,
server: myserver.somewhere.xx, request: "GET 
/imp/dynamic.php?page=mailbox HTTP/2.0",
upstream: "fastcgi://unix:/run/php/php8.4-fpm.sock:", host:
"myserver.somewhere.xx", referrer: 
"https://myserver.somewhere.xx/horde/services/portal/"

Why is that?
