Hello! and welcome to the Black Mesa...

Sorry for new long post, but it is very interesting project to me and I want to help it in a way I can.
After some experiments with autolinkink patterns I found strange error on inserting any new line to existing autolinking patterns:

(ru|en)wiki:((.+))

http://help.local/question/\1

It all starts when I try to use supergreed quantificator (+) in pattern regexp. When I change/delete any (first or last) pattern or add any new line - error shows up. When I delete all patterns, reload page and add one or all patterns again, all works fine but only if I don't change patterns again.


Next strange thing is when I delete all the patterns (and leave an empty field) they don't remove from DB:

mysql> select * from livesettings_longsetting where livesettings_longsetting.group like '%MARKUP%';
