Moodle version? PHP version (WAMP version if you like)? Installed from a moodle.org download or is this an install script of some sort (which)?
>> Downloaded latest moodle '2.4.1+ (Build: 20130118)'
>> WAMP Server 2.2
Any modifications to Moodle?
>> No , no modification done
What where you doing when this happened?
>> I was installing moodle with web interface provided, created DB manually and after I entered DB name, passwd to web installer it happeded. I checked DB but no table was created.
Thanks for helping.
