After upgrading to WP 2.8 we are experiencing a lot of problems when we try to write new posts.
1. upload images/video buttons - nothing happens when clicking those, nothing at all.
2. Custom fields - when we try to add a new or use an old custom field key/value, the page is reloading instead of using the Ajax functions. When it has reloaded the values aren't even there.
3. Post Tags - same as above. Page is reloading when adding an tag, instead of using Ajax.
I'm pretty sure there's more, but you get the picture. This is kind of important to fix for us, we are not able to write new posts before it is.
Please, if you know a solution for this (we'll try anything before downgrading) - answer me :)
