applying leave problem - internal server error

applying leave problem - internal server error

Hi!


We have just started using Zoho People and are quite satisfied, still we have problems with adding leave (Leave Tracker/Vievs/Apply Leave). After we have filled all places with proper data and we try to submit it "internal server error" occurs. It happens no matter what date we try to set. Is it us making something wrong or are you having some problems on your side? 

Thanks in advance for your support.
