ExternalAuthenticator keeps refreshing and looping round

I am ot sure it this a TinyMCE issue or Drupal.

My site has just been moved to a new server and I am having a few issues, one is when I browser fro a file or image the browser windowm just keep refreshing.

Going to the auth_drupal.php posting then back to the auth_drupal.php. The key data in the auth_drupal.php is the same as in the config.php files.

Does anyone have any ideas.

The only changes is the server I can see is I have gone from PHP Version 5.2.14 down to 5.2.11.

Should I ask them to upgrade?

Cheers,

Angela.
