I accidently put in a few "<"-character in function.php in the Twentyeleven folder with the WP theme editor (pasted in some code from a tutorial) and managed to save it, but now the whole site crashed due to the "unexpected '<' in function.php", including the dashboard.
Thing is, all I need to do really is use FileZilla to open and edit the file to remove the bastardous characters and then be moisying along again. But I can't... Because the folder permissions is set to 755 and the function.php is set to 644 and I only get a "550 operation not permitted" when i try to chmod them. That folder - and all the files in it - is the only thing on my whole serverspace that won't let it self be changed.
Why is that? What made it that way? And what do I do to fix it? Isn't it a bit strange that it would be updated through the WP editor? That makes me think it's an ownership issue, which I wouldn't know how to deal with either... :S In either case...
