I just upgraded from 3.9 to 4.0.5 just to have problems. At least, 3.9 was working. I'm unable to take simple actions like:
1- Rename a page: I duplicated one of the pages which was created in 3.9. Edited this new page in 4.0.5, but can't change its name after trying so many times. The name always goes back to the original state after refreshing the list.
2- Viewing a list of pages: No matter what I do, I can only see a total of 7 pages. 6 pages were created in the older version. 7th page is a duplicate. If I change the sorting to anything on the dropdown, I can see more pages.
3- Duplicating a page: I kept tyring to duplicate pages. Even though it said success, I wasn't able to see the duplicated pages. Because of the issue #2, I wasn't able to see them.
4- Trashing or Unpublising a page: I ended up duplicating several pages. I am unable to rename them. I tried to trash them which failed. I tried to unpublish them which failed.
These are simple actions. 4.0.5 made me frusturated with these simple actions. Forget about the visual editing. I want my old version, so at least we can continue creating and editing pages!!!
I cleared the cache on Joomla. I cleared the cache on the server. I cleared the cache on my browser. Nothing worked!!!
