Hi,

• Which MediaWiki version is this about?
• Why do you think that ContributionScores creates the "notice" (not: error) above, as there is no mention in the output?
• Why is this a "blocker" priority?

• It only happens, when the Extension is activated via require_once("$IP/extensions/ContributionScores/ContributionScores.php");

Further the message only occurs when loading the Special Page Constribution Scores.

• Thought it is a blocker since I cannot use the Extension in this case - although it is not blocking MediaWiki. Didn't know what could be the right priority since I'm only a user, not an extension developer. :)

since I cannot use the Extension in this case

Can you explain why and how you cannot use it?
Asking as it's not an "error" technically, but a "warning" only.

The extension will create a list of scores for each user. This list is shown on a SpecialPage. When I try to open this SpecialPage the error occurs and the list is not shown but only the error message.

If it is a 'blocker' depends on the point of view.

From the point of view of MediaWiki itself it is no blocker - the wiki is still working.
From the point of view of the extension it is a blocker, since the extension cannot be used.

I hope this cleared the status of this bug.
