I use the component for a long time and all other templates works perfect.
I have the latest version 6.5.5 and joomla 3.5
Today i created a new field map and when i click to create a template i get "Internal Server Error"

1st post update after some more tests
1. I can create the field map normally with no problems
2. I can create manually the template and then add manually one by one the fields
