Hello Alex,
Thank you very much for your reply.
As you know, my GD site is the main site of a multisite network.
I have looked at the wpconfig file and I can not find any line about revisions.
However, revisions are enabled in the other two active sites of the multisite network.
I can not find any info about this matter looking for “revisions configuration per site in multisite” and similar strings in Google.
I know that this one is not strictly a GD question but, since my GD V2 site inherited the disabled revision status from the GD V1 version of which it was a GD forced setting, I would appreciate very much if you could help anyway.
I look forward to your news.
Thank you very much once again for your help.
Best regards.
