Status: Unverified Fix
SQL error on trying to approve style (see attachment for full error).
After the error, a topic was created containing only a post by me "Style has been updated to version 1.0.0". There was no normal first post created (containing all the style info), nor the post reserved for the author. In addition, it's even a new style, not an update.
Now if I try to go to the validate tab I get "No pending data found, Style isnt in the queue?" and the overview page shows a link to the queue topic and no announcement topic.
