Ran across a bug in the events config page that I thought I'd pass along.
It seems like if you save the configuration without having any extcal settings set, it causes an error which dumps the script with an unexpected ; error message.
For some reason the script's removing the "" when it edits the mls_events.config.php file on at least lines 2 and 7 (extcal_category and extcal_approve_mode). A quick fix is to hand-edit the page to add them back in, but I'm sure that's not how it's intended to work.
I'm pretty sure my install is up to date (at least for the main downloads), running 0.1.5. Let me know if you'd like me to test any fixes for this.
Thanks again for a great piece of LAN management software!
