Thread:Project:Support desk/404 errors after upgrade from 1.15 to 1.20/reply (2)

Hi....thanks very much for answering. Can you tell me how to "run the file update.php in the maintenance directory to update your database". I know it must be basic information, but I'm so new at this, I have to ask dumb questions to be sure of myself... :-) Thanks again for all your help!!
