500 Internal Error on Every click

Hi,
I really dont know why i am getting
500 Internal error again and again.
I had hosted suitecrm on IIS 7 with PHP
Server Windows 2008
Database MSSQL

Please Help

Was this working well before? What did you do when it stopped working (upgrade?)?

Which SuiteCRM version is it?

You should look in your Event logs to see which PHP error is behind that 500 web server error.
