Handling with incorrect jDownloads DB table structures

[Arno]

Since the beginning of the pre-beta phase, beta testers have reported database error messages after the update. I could not reproduce many of them in my case.
My testing then found that there were users working with jDownloads database tables whose definitions were incorrect.

As a result, I have already slightly adapted the update script and at least taken into account the most frequently occurring variant and cleaned it up during the update.
Now the tables are checked before the update and are aborted depending on the error finding. As far as we know, the number of users affected by this is very small.

For another possible error variant, which has to be cleaned manually by the user until further notice, I have created a short PDF instruction (see attachment).

The error message in this case is something like:

A check of the jDownloads database tables revealed differences from the expected data structure. Therefore, the update was cancelled.

Check the tables for correctness. Use the documentation and/or the jDownloads support forum to solve the problem.

The Table: #__jdownloads_files has an incorrect number of data fields. This means that an update can probably not be carried out without errors.
The data fields listed below are not in the correct position within the table. Therefore, the update was cancelled.
