@ miko i have checked mysql database, checked and repaired and it still ask me to fill in username and password
and i don't know why it still does this please can you help
Disregard what I said above...
I'm just going to go out on a limb and assume it's a fresh install and your not importing from something else. If it's a fresh install - If you are just unable to log in:Go to your msql database. Look for the smf_members table. Browse to view all members. Look for admin. Go to edit the admin fields.
Change the password in the password field (there should be a hash code of some sort - just delete it and then put in a new password)
Save.
Go back to your forum and try to log in as admin with the new password.
but ...If you are able to log in but not able to access your admin panel: Go to your msql database. Look for the smf_members table. Browse to view all members. Look for admin. Go to edit the admin fields.
THEN
look for this field: ID_GROUP smallint(5) unsigned
Make sure that the value is "1"
Save and then log back into your smf and try to access your admin panel.
I hope one of these options will be of help to you... It's just my best guess without more specific information about your site.
