I've got got a weird and maybe stupid problem. I have problems with the character encoding for my (german) blog:
With UTF-8 it looked fine even with ö, ü and ä characters as long as you were viewing the site with Internet Explorer. In Firefox however it always looked screwed up. So I tried changing the character encoding using wp-admin/options-reading.php
Since I'm a layperson, I just tried one coding after another, reloaded the blog, changed again and so on.
Now all of a sudden it defaults to UTF-7, no matter what I do. I cannot change anything anymore. When I change it and press "Update Options", it gives me a summary site of all options being set, with UTF-7 still set.
I also cannot sign out anymore, nor change my profile.
It seems something's been royally f*cked up thanks to my stupidity.
Now my simple question is: what could be causing this, OR where does it write these settings to, anyway? What is the name of the file I need to open using my FTP program, so that I could change these settings using a text editor?
Many thanks in advance!
