Description:
Problem happened on upgrade from MW1.16.5 to MW18.
I downloaded the most recent version of DPL from the Semeb website (1.8.9).
The error is:
Fatal error: Call to a member function addMessages() on a non-object in xxxxxx/extensions/DynamicPageList/DPLSetup.php on line 1163
Any page which has {{#dpl:...}} or <dpl></dpl> crashes in this way. Other pages are fine.
Version: unspecified
Severity: critical
