Appointments + bug when adding a new service provider

I'm currently translating A+ to Hebrew. While testing my site, I went to Settings > Service Providers, clicked the Add New Service Provider button... and nothing happened. I removed the mo+po files, and it worked. Put them back, and the buttons stopped working again. Funny thing is, I haven't translated this page yet!

One more bug: I tried to attach the language files, but the system won't accept mo, po, OR zip files, the po file is too big for text, and it won't let me fake it as a png... Please let me know how can I send you the files.

TIA, Assaf.
