Hi folks!
I run WordPress 3.3.1 at a couple of sites and different hosts w/o problems, but one install is troubling me. It's one of two installs in the same hosting account/on the same server that doesn't work. So it doesn't seem to be a hosting related problem.
I can reproduce the errors in different browsers, too. Disabling all plugins as well as using the default WordPress theme didn't help. A manual install of WP 3.3.1 after deleting the wp-admin and wp-includes folders before didn't fix it either.
My errors:
1) When I go to MEDIA => Add New, I'm able to upload images. However, if I try to add a featured image or upload images on an "Edit Post/Page" page by clicking on the Media Uploader icon, the media uploader doesn't load.
2) The wp-login.php file is missing its styling. I took a look into the source code, and the CSS files are there, but compared with a styled wp-login.php the following code is missing from the head part:
<script type='text/javascript' src='http://mysite.com/wp-includes/js/jquery/jquery.js?ver=1.7.1'></script>
3) The toolbar doesn't appear correctly. In the admin panel I don't see the WP icon nor the Comments icon nor the plus sign before "New". And on the site itself the toolbar looks more like the toolbar before WP 3.3, and the search code is not right-aligned and so on.
4) There are some other "unstyled" sections in the admin panel.
I assume all errors are related and are all more or less a JQUERY problem. But I can't figure out why this problem occurs to begin with and how to fix it.
Thanks for any ideas you've got for me.
