"Add Module From Directory" and other module installation methods not accessible

[Christophe]

Hello,

I just installed a fresh new ProcessWire 3.0.243 instance on a (not local) web server. The PHP version is 8.2.

"Add Module From Directory" or any other method is not accessible even with debug mode activated (acknowledged by the backend).

For "Add Module From Directory" :

• with $config->debug = true; it only displays :
  This install option is configured to be available only in debug mode. To enable, edit file /site/config.php and specify:
  $config->debug = true; temporarily …or…
  $config->moduleInstall('directory', true); to enable always
• with $config->debug = false; (or $config->debug = true;) and $config->moduleInstall('directory', true); it displays:
  This install option is currently disabled. To enable, edit file /site/config.php and specify:
  $config->moduleInstall('directory', true); to enable always …or…
  $config->moduleInstall('directory', 'debug'); to enable in debug mode only

I can of course do it manually via SFTP, but I would really like to have that option like I had before on other installations and to know why I don't have access to it.

Has anybody had this issue even with $config->debug = true;?

It's not that something (like a hosting provider's firewall for example) is disabling this possibility of downloading from the backend (it already happened and I just had to deactivate the firewall).
It's that it doesn't even show the input field to enter the module class, just these messages.
