Hello Adriano,
First of all, sorry, but i entered the problem in the marktetplace review. I thought it was the support. I removed it there.
The problem was when installing your addon, i got some errors, and after that the admin side was not responding.
Then only error i got was
[[Template core/admin/global/globalTemplate is throwing an error. This theme may be out of date. Run the support tool in the AdminCP to restore the default theme.]]
I put the Theme database entries from yesterday back, and everything was ok.
But i want to use your program but how to act now??
Henk
