Can’t do new posts! :(

Everything was working fine and then all-of-a-sudden… I can’t write or edit any posts. The WP dashboard works fine except when I click on the Write tab, the Write Post page tries to load up but freezes. Same with Edit. I click on Manage and it goes to the list of the posts I have but when I click on Edit, same thing; the page tries to load but freezes. I have no clue what’s going on. The site works fine and the WP Dashboard works fine except for the errors I mentioned above. Anyone can help?
