I wrote greeter1 instead of greeter=1 but now I have a new error which is really one
Database error in vBulletin 3.0.3:
Invalid SQL: UPDATE user SET posts=posts+1 WHERE userid=4
mysql error: Table 'usr_web1_3.user' doesn't exist
mysql error number: 1146
Means you've once forgotten to check for table prefixes in this line
UPDATE user SET posts=posts+1 WHERE userid=4
Can you update this and tell me what to change?
