What do you mean upgrading your forum would not make photos disappear?
Did you upgrade your photopost if so you ran 485 upgrade more than once to get photos back you restore a backup of your photos table and run each upgrade ONCE through from your last version.
Thanks Chuck S for your reply but I think you got me wrong,
I've upgraded vbulletin to 3.6.3 not photopost.. An my gallery is empty now..
( actually 1 photo is left there.. )
Do I have to run any script from photopost to bring things back ?
upgrading your vbulletin forum would never delete your gallery thus is what I have posted above so if you would like support please post some links to your gallery so we can understand what your asking.
