After an administrator edits a member's post, the admin appears as the submitter of the post, not the original user. Also tested on a fusion test page.
(I suggest a new forum tag for the forum filter on this site: V9.1)
Okay confirmed, so far only this doesn't work correctly in new v9.10. Maybe in next month we will release 9.10.10 with additional fixes.
Btw. there was a public beta test for these cases, but no one tested entire system.... For info, I will not do these beta tests anymore because it's useless if no one test everything.
