"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.

Using this in /site/config.php

$config->debug = true; // or false, doesn't matter
$config->moduleInstall('directory', true); // this is important
$config->moduleInstall('download', false);
$config->moduleInstall('upload', false);

allows me to use the directory to install modules.

Thanks, but it doesn't work for me.

I see that in wire/config.php the default is 'directory' => 'debug', 'upload' => false, and download' => false.

So

$config->moduleInstall('download', false);
$config->moduleInstall('upload', false);

shouldn't be necessary if I want to download from the Directory.
And I suppose all the "Add" methods could be activated at the same time (?).

For "Add Module from Directory", the default(s) seems to confirm that you just need $config->debug = true; and the directory will be available only while debug is on true, or $config->moduleInstall('directory', true) and it will always be enabled.

On the Modules page (in New) the notes change depending on what is enabled in site/config.php.
By default for "Add Module From Directory":

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

So, just adding $config->debug = true; should work as what corresponds to $config->moduleInstall('download', debug); is the default.
Or $config->moduleInstall('directory', true); to make it always work.
So both can of course be present.

But nothing works for me, I never see the Module Class Name area.

I can't figure out why for the moment.

Permissions are usually 755 and 644.

I found why it wasn't working after installing the Upgrades (ProcessWireUpgrade) module. 

The Upgrades module warned me with ProcessWireUpgrade: Your PHP does not have ZipArchive support. This is required to install core or module upgrades with this tool. You can still use this tool to identify new versions and install them manually.

So I just had to enable the Zip PHP extension that was not activated by default.
