Well, it does not look like it work?

There is more below about a stack trace:

ah and I tried with 50 config=>array( enabled and with the ' in front of it (like it was before)

Sorry, the pasted error message is not very clear to me. Can you do a screenshot instead?

Thank you. Did you update from a previous version of LS, or is this a fresh install?

It is an old install (2.x) with about 60 or so questionaires.

When I updated it to version 4.x I followed this:

Delete all the old files/folders except for:

/application/config/security.php -Important!! This is the key to all encrypted data in LimeSurvey (version 4 and later)
/application/config/config.php;
/upload directory

I did afterwards the one month of comfort update, followed by manual updates, always following that guideline, backup DB, delete whole folder except for those files/folders, copy the new version in with ftp software

Your best bet is probably to add the file manually from Github: https://github.com/LimeSurvey/LimeSurvey/blob/master/application/core/plugins/AuditLog/config.xml

I tried to change the config from the AudiotLog, no change.

I looked into the xml that generates the error:
(/application/models/Plugin.php(111))

public function getExtensionConfig()
{
    $file = $this->getDir() . DIRECTORY_SEPARATOR . 'config.xml';
    if (file_exists($file)) {
        if (\PHP_VERSION_ID < 80000) {
            libxml_disable_entity_loader(false);
        }
        $config = simplexml_load_file(realpath($file));
        if (\PHP_VERSION_ID < 80000) {
            libxml_disable_entity_loader(true);
        }
        return new ExtensionConfig($config);
    } else {
        throw new \Exception('Missing configuration file for plugin ' . $this->name);
    }
}

I have PHP <8 (7.3.6). I could update PHP to 7.4 could that solve it?

PHP version shouldn't matter, no. Strange.

Can you list the files in the AuditLog folder?

This one?

Updated to 5.0.0 (build 210526): Error still there.

I did again a clean install, onlything I kept is the config.php the security.php and ofc my database. All the rest is from the latest .zip

Very strange.

Can you change this line

         throw new \Exception('Missing configuration file for plugin ' . $this->name);

to

         throw new \Exception('Missing configuration file for plugin ' . $this->name . ' ' . $file);

And then try again. Copy-paste the error message here. This will show exactly where the system was looking for the file.

Does nothing? Did I miss a space or something?

No, it works. In the error message you now have the exact file location expected by the system to find config.xml. So, move config.xml there. :)

Thank you so much. I don't know why it wants the plugins in this folder and not the other folder. But after copy/paste it works now!

You probably had an old installation? We've been moving old plugins to new locations. This explains the issue, at last. :)

Yes, I took over an old installation of version 1.9 with a lot of old questioneires and a really old template.

OK, that makes sense.

Closing this for now.
