Can't Downgrade!

Hi! I recently upgraded to 4.1.65. One of the reports, isn’t working on it and hence i wanted to downgrade. Now, i renamed the setting.txt file, unistalled samba pos and installed 4.1.58 but no matter what i do it won’t run. Please help!

There are lots of changes & fixes between 58 and 65. Fixing the report issue will be a better solution. I think @gerlandog answered the report issue.

btw you can’t downgrade without a backup.
