Hi Ezequiel,
We've seen this behavior on various shared hosting sites with tight security settings - empty page that is caused by "500 - internal server error". It is difficult to say what is exactly the problem in your case, please take a look at your Event log on the server - it will probably contain records with detailed error description. Send the error description to us for further instructions.
Which version of Windows Server and IIS are you using?
Thank you very much for your reply, really expected.
At the moment I cannot access the log server, since I do not have permissions to access them. However I can tell you that the Windows server is version 2003 and IIS version 6.
If you could tell me which would be the ideal setting to monox software work I would be of great help, so can I install the soft configuration you indicate me.
Regards, Ezequiel.
