If your global option mysqldump command is entered right and the file is indeed altered accordingly it should work fine.
no, I did not mean the īcode change in the adm-backup file. I mean the original upgrade script of PP4.85 which is in the original zip file of 4.8.5
In the announcement of version 4.8.6 it was mentioned, that you replaced various upgrade scripts with only one:
"There is a new upgrade.php script which can be used for all future upgrades; however, the upgrade from 4.85 to 4.86 does not require any database changes." PhotoPost 4.86 Update posted
So if I could download the original 4.8.5 zip file, I could try to upgrade first to 4.8.5 to see whether the problem exists already there.
Again, all my other installations on the same server do not have this backup problem. But they are all version 4.8.2.
