Issue : Not sure if anyone had this issue before, but hopefully someone has and has a workaround/fix for it.

While I am in wp-admin area, I will randomly get redirected to my main blog URL with a Not Found message.

Anyone experience this and know of a fix?

Solution : Try deleting your .htaccess, change your perma links and change them back again allowing wordpress to write your .htaccess again . Im not entirely sure if that will fix it but its an idea to start with as usually when i have redirect issues its normally a permalink issue or a missing file somewhere
