Hey, I have just converted my forum software and now the passwords no longer work on the new board so I need to set my admin password up to get it all sorted. How can I do this?
Make another PhpBB3 Test Forum. You will be the only user there. Keep some password w/e it may be. Then log into your PhpMyAdmin and if i am not mistaken, enter your PhpBB_users Table. Copy the MD5 Hash for the Admin password. Then go back into your old installation (whr the password is not working) Database. Enter the PhpMyAdmin > phpbb_users > and edit your admin passwords MD5 Hash and paste this one. Your pass should be changed to the one pertaining to the new table. Try logging in.
On my PHPBB3 forum I could apply the following solution: create a new user with the password you want to use go to phpadmin and copy the md5 hashed password from the new user to your admin user login as admin user with the password you filled in in step 1 Done !
