Hello,
It's quite difficult to say what should be wrong without any hints.
Are you sure, that the eTicket installation was successful? VM must be installed first.
You can check if all files (including VM configuration) has correct access rights.
Then try to check Apache error log, if some errors are there.
It should be because of some VM module, that trys to include VM config file (but they check it incorrectly). But this error usually end by some error message.
I see, that you have some programmer knowledge, so you can put some information texts into the code and see, where is the problem (which text will not be displayed).
If it won't help or you'll explore some difficult problem, please, write me again.
Have a nice day, Pedu.
