My blog is currently experiencing these problems:
* Some readers cannot view the comments template and other Single Post functions which load after that template.
* For those users who can, when they try and leave a comment, the response is "Bad Response From Server"
* In the admin, some of my Dashboard, Plugins and Options pages are completely blank
* When trying to post, one blogger is given the option of downloading the PHP file they are trying to post.
Lots of strange errors happening at once.
Is this a server issue? Hosting issue? Would the server itself had a problem with some of the PHP?
