Thread:Project:Support desk/How do I access Maintenance scripts?

I have installed mediawiki 1.8.1. It works fine but I am not able to access the maintenance scripts. I get "access denied". I have read many pages on this subject (and used Maintenancetool extension which does not work). Is there someone that could explain me ho to solve this issue? Step-by step: I am not familiar with sql etc. Thank you. Emilio
