I've been working with WordPress for quite a while now. I have installed and upgraded in the past quite a few times and have always had multiple wordpress-installations on one domain at the same time. Never any trouble, it always worked perfectly.
Today I tried install WordPress again on my domain. I have 2 other installations running without problems. The installation of today didn't give any problems, it went perfect. But when I log in to the admin-panel the problems start. In the "write post" screen there should be a WYSIWYG-editor but now it isn't. I can post, but it's not how it's supposed to be. Internet Explorer reports problems with opening the page.
When I go to the "authors and users" page in the admin-panel, it remains completely blank. Again Internet Explorer reports problems with opening the page. The "Your Profile" page for the adminaccount shows in all fields the value "Array". These are also thing I have never had before.
I installed/deleted and reinstalled/upgraded several times (both files as database) today but nothing seems to work. The installation somehow seems corrupt and I couldn't find anything on the web on how to solve this.
Please, can someone help me?
Thanks a million!
