Topic on Extension talk:StructuredDiscussions

turns out i failed to implement custom namespaces in LocalSettings. I decided I didn't want them or the few pages in them anymore and thought it would be ok to just comment them out. I was for the most part, however, refreshLinks was trying to refresh the talk pages that had no active namespace and that is what was crashing it. I have reenabled my custom namespaces and refreshLinks is running without errors. Hope this helps someone.

When I run:

sudo php /opt/htdocs/mediawiki/maintenance/refreshLinks.php 1080 --e 1087

I get the following error:

/mediawiki/maintenance/update.php runs without error

The Talk page works as expected.. it's just the refresh links that is failing.

Please advise. Ty
