Could i download 3.6.8 and replace 3.6.5 with 3.6.8 this method feasible for upgrade from 3.6.5 to 3.6.8?
Is this the first time you are upgrading? All the upgrade instructions are there in the vbulletin files. It is a simple procedure. Just back up your logo etc.
Actually sachen410 is right but one thing that might be of inerest is this: If you are at 3.65 and you uprade the system, which is what you should do if you do not have a bunch of intense mods or a custom template, the installer will first upgrade you to 3.66 then to 3.67, and then to 3.68 which is pretty cool! VB is a fantastic system and you should be fine! If you need help or are a little freaked, PM me!!
Did i succeed in upgrade? my index footer show 3.6.5? from admincpanl show 3.6.8 I found member list page become error page http://www.adulu.com/member.php?u=1 what's up?
It's your MySQL problem. Whenever VB has SQL connection or database problem then that error shows. You might have modified the SQL database..
Is your sql size is huge ? It seems that your database is not lost as all other stuffs are working well. However, there maybe some error which might have created during upgrade or while installing any mods and which is causing the error.
thanks for AlTeC's opinion. I just back to upgrade from 365,366.367,368 one by one which could working fine. thans for everyone.
