Proper Ludwig usage for multisite installation

Hi Jochen.

Please send a bit more data about your config.

- Your Ludwig version
- Drupal core version
- php version

Running Drupal 10.1.6 on PHP 8.1.26.

Modules:
Ludwig: 2.0.6
trying to install "Drupal Symfony Mailer" 1.4.0

It's the latest version of Drupal and all modules. No warnings and errors on the status-log.

I tested.

I get the same error if I try to install Drupal Symfony Mailer module BEFORE all packages are downloaded by Ludwig.

After all packages are reported as downloaded by Ludwig the Drupal Symfony Mailer module installation goes smoothly for me. No more WSOD or errors in logs.

My log record. Screenshot attached.

According to Ludwig, everything is in place, so where is the difference?

Is there a way to share a file listing from a working installation?

Also, afaik, Ludwig can't install libraries on it's own on a multisite installation, can it?

I don't have any experience with multisite configs,

so where is the difference?

You can try to clear caches at all your sites after visiting Ludwig Packages page... just in case that's the problem in your case.

Is it possible to post a directory listing for comparison?
Should be enough to get it of the /libs folder.

Did you try this suggestion?

Also... at your multisite configuration... do you have a multiple modules/symfony_mailer folders or only one for all sites?

yes, clearing caches worked in fact..

Good to know. Now I feel stupid.

Glad this helped.

Ludwig has a cache clean embedded into it's code... but it can cache clean only the cache at the site where you have visited the Ludwig > Packages page. At all other sites you need to clean caches manually.

The same drill with cache clean (at all your sites) you will need to go through after updating the symfony_mailer (or any other Ludwig-managed module) next time.
