Have a look in the MODX error log and the server error log to see if there's a reason for the 500 server error anywhere.
Just tried it and it's working fine. Are you absolutely sure that you did the
initial installation of MIGx correctly?
@Mark: Unfortunately I've cleared the Error-Log while finding the problem, to get just the fresh errors.. and now - the log stays empty.. even if I play with the migx-configs, the templates, the tv and other options that could cause the error..
@Susan: I've done the installation (inlcuding running the setup on CMP) correctly I think.. The MIGX CMP is also working fine - just as my normal MIGX-Configs.. there is just the problem with the MIGXdb-TV..
@Mark/Susan: If you want to have access to the manager to see whats going on send me your email and I give you acces ;-)
FWIW, 500 errors will most likely not be reported in the MODX error.log. You would need to look in the error_log specified for PHP on your environment to find this error in most cases...
