Permalinks case problem
Just spent an age working out why a permalink prefix was saying it was missing when it wasn't, part of the plugin processing sets the permalink to lower case and then compares the required prefix, fine so far but the check doesn't ensure that the original prefix is set to lower case.
So if you set the required prefix to 'Activity/' the comparison is never going to succeed!
Thanks for the bug report! I'll have to think on the best fix for that. What are your thoughts? Should be lowercase the prefix before we display it? My concern with allowing mixed case is it's not portable (some servers are case-sensitive and some aren't).
