"Missing 'Sites' Tab in ISPConfig – Reconfigure Fails with DB Error"

Hi,

I'm running ISPConfig on a Debian 12 server with Nginx, installed via the autoinstaller using these flags:

Code:

--use-nginx --no-dns --no-mail --no-firewall --unattended-upgrades --i-know-what-i-am-doing

I have several servers installed this way, and everything worked fine until recently. I noticed that on one of the servers, the "Sites" tab and a few others are missing. I'm logging in with the default admin user, and I also tried creating a new admin account — the tabs are still missing.

I even set the default start page to Sites, and it loads correctly (the module works), but the tab still doesn’t appear.

Here’s how it looks:




After checking documentation and community suggestions, I tried to re-enable the modules by running:

Code:

ispconfig_update.sh

I selected the stable channel and attempted to reconfigure services. However, during the process, I received the following error:

Code:

PHP Warning: Trying to access array offset on value of type null in /tmp/update_runner.sh.EDU3XOltRc/install/lib/update.lib.php on line 147
PHP Deprecated: stripslashes(): Passing null to parameter #1 ($string) of type string is deprecated in /tmp/update_runner.sh.EDU3XOltRc/install/lib/update.lib.php on line 147
Unable to read server configuration from database.

Things I’ve tried:

• Verified MySQL root access works.
  
  
• Checked that /usr/local/ispconfig/server/lib/config.inc.php has the correct DB credentials.
  
  
• Tried re-running the installer interactively — got a warning that it would overwrite the whole server (I can’t risk that).
  
  
• No backups available.
  
  
• Verified the Sites module is present in the filesystem and expected tables exist in the database.
  

System:

• Debian 12 (Bookworm)
  
  
• Nginx setup
  
  
• ISPConfig 3.2.12p1
  
  
• Installed via autoinstaller with --use-nginx, --no-dns, --no-mail, etc.
  

Question:
How can I safely restore the missing Sites tab/module without breaking the current configuration?
Can the server table be regenerated manually, or is a full reinstall required?

Any help or guidance would be greatly appreciated.

Thanks in advance.

 

All modules are enabled, also checked at the DB

 

And like I said, I have set the default start page to Sites, and it loads correctly (the module works), but the tab still doesn’t appear.

 

Recently I saw the error — the server table in the database was empty. I copied it from another server, changing a few names, and now the interface appears correctly.

But now there's another problem: when I create a site, it shows up on the web, but on the server the site's path doesn’t exist. Also, the task number (the red circle with the number) doesn’t appear — not when making changes or anything.

Any idea where I should look?
