I decided I would finally upgrade to 2.7 (http://andreasaronsson.com), and I was surely impressed with the new interface, though I soon cried blood.
When I began editing a draft I was planning to post today and fixed a typo and saved, I noticed that the typo was still there! Then I noticed that it was true for all edits, they were really hard to get saved. A change would be saved after 3-5 edits.
I am not sure what is going on, but it is really frustrating. I have also tried to reverse the order of the pictures displayed in a gallery in that post, and after a while it did not matter if I chose ascending or descending, the images were always in the same order.
Am cry :( If I cannot get this fixed I will so revert to 2.6.5...
I figured it could be Google Gears or WP Super Cache, but disabling both makes no difference. I even disabled all plugins, and still no difference.
I did forget to disable my plugins before upgrading, could that cause a weird problem like this? Should I restore my backup and upgrade again?
