I was wondering.if this was a problem that coul occur... Say someone signs into a wordpress website and makes some changes to the content, saves it and then doesnt sign out of the account. Then someone else signs in to the same site on another computer using the same admin login and makes some changes to the code (maybe stylesheet), saves it and then logs out. Now the first person who still hasnt signed out comes back and makes some more changes to the content and saves again... Would this cause the changes made by the second person to revert back to what the first person is doing as the first person never signs out and both are using the same login? Can this cause problems? Thanking you in advance!
IF the first person left the same window with the same edit box open, it is theoretically possible -- it would come down to how well turdpress maintains a record of edits BEFORE saving changes; something given it's track record of "insecure by design" and "data locking, what's that?!?" development methodologies I very much doubt it does properly if at all.
The point is: If a person logs in, does some edits to a post, and saves it, the work is saved (same goes for pages, files etc). However: if another user signs in AS WELL, while the first person is working, but before the content is saved, then that person will get the original content up in his/her edit-box - which will mean that content could possibly overwrite other stuff. The content will not update in real-time (not even when it's saved), so this is a potential pitfall. However, Wordpress WILL keep a revision history, so it will be possible to go back and look at the changes made, and do a manual merge.
