Troubles upgrading to 5.12
I am currently running Vbulletin 3.07 with Photopost 4.86 vb3 Enhanced. During the upgrade from 4.85/4.86 to 5 it says it will move files in the DATA folder and that it might take 10 minutes for 10,000 files etc and that we can refresh the page if the process is not done (upgrade.php?upgrade=485&step=2). I waited about 7 minutes then it said the process was done and I could go to the next update (upgrade.php?upgrade=485&step=3). Instead of coming back to the upgrade page with all the links, I got a "the system experienced an unrecoverable error".
I went back to upgrade.php?upgrade=485&step=2 to refresh the page to see if it will fix but this time I got the "it is done" message without even waiting.
At this point, I went to upgrade.php myself and then clicked for the next upgrade and it worked fine until the end. I went to the admin panel and it said it was running the 5.12 version. The problem was the statistic showed 0 photo when I had over 30,000 photos and of course I had no thumbnails with no photos...
I reinstalled the old version from the backup and it is working fine again.
I am pretty sure I following all the instruction fine and I did upgrade fine another photopost I have from 4.86 to 5.12 without any problem. The only difference between the two photoposts is the number of photos (32,000 Vs 600).
How can I fix this problem to be able to upgrade?
