I'm no expert in OTRS, but maybe it's a Linux permissions issue?
Your OTRS files and dirs need to allow access to both user OTRS and group APACHE - at least that's how my installation is and it's working fine...

Hi
this is my first post. I've searched previous posts and googled for
this issue, but I can't get a solution yet.

the issue is that when a customer clicks over a ticket, instead of it,
an error message is displayed:
********************************************************************************************
Oops! An Error occurred.

Error Message: No Permission to use this frontend module!

I have been reviewing the System parameters for a couple of days, but
I still don't find where the permission got lost...
I'd appreciate any help...

Thanks!
