[Plugin: All in One SEO Pack] Posts return blank pages

Hi

When I activate the plugin, clicking on posts give blank pages. When I view the source in the web browser, there is nothing there. All other pages on the site seem to work ok, its just the posts that are returning blank pages. I have not yet field in any of the fields in on the preferences page.

PHP errors are setup to show on the page and I get none, so I’m guessing there is no error. I’m running the latest plugin version (1.6.10.2) and the php version is 5.2.6 running on linux shared hosting. Even when I disable the plugin from the SEO options configuration panel I still get blank pages.

Any help appreciated.
