ISPconfig do not work, after login logo+search box and blank page

Hi Till
thank you for your help and great work. I'm using with success ISPConfig since several years. Now I have a problem: the ISPConfig interface is stucker.
When I connect all is fine, I insert username and password, click the button to access and the result is a blank page where I can see only the logo (top-left) and the search box (top-right).
Since today ISPConfig was running ok.
It seems that is happened after installed PHP8.1+fpm, all was made following the tutorial:
https://www.howtoforge.com/tutorial...fig-3-from-debian-packages-on-debian-8-and-9/
The errrors showned by /var/log/apache2/error.log are the following (tail):

despite the configuration in /etc/apache2/sites-available/ispconfig.vhost:

<IfModule mod_fcgid.c>

</Directory>
IPCCommTimeout 7200

and however inspecting the wrapper that's ok

# more /var/www/php-fcgi-scripts/ispconfig/.php-fcgi-starter
#!/bin/sh

I've reinstalled latest version but nothing is improving.
I suspect that there is some misconfiguration and that ISPCONFIG is running with the latest PHP8.1-fpm instead a 7.3m as spected.
Note that I have this daemons running
...
php7.3-fpm
php7.4-fpm
....

and then PHP7.3 is up and running:

thank you for your help

 

thanks, I read and changed using alternatives, without success.

PHP version is wrong.

Code:

##### VERSION CHECK #####

[INFO] php (cli) version is 7.4.28
[INFO] php-cgi (used for cgi php in default vhost!) is version 7.3.33

They should be the same and for Debian 10 default PHP is 7.3.
If you have additional PHP versions installed, remember
Code:
update-alternatives --config php
and
Code:
update-alternatives --config php-cgi

 

fixed but again without success, see here:

more this is very annoying, infact this morning I configured 5 servers with the same procedure and only the last ISPConfig interface still broken. Here the output of the latest row of the generated HTML:

<!-- Datalogstatus Modal -->
<div id="datalogModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">

<h4 class="modal-title">The following changes are not yet populated to all servers:</h4>
</div>
<div class="modal-body">

remember that this happens just after made successfully LOGIN.

 

ok received and resolved. Should restart apache!
Forgive me for this (I'm stupid, fall in this after several years of work...)
now I'm going to document this issue for the future

thank you very much for your help!
