You were right that sorted out the error but not the blank screen.
Blank screen cased by memory issue.
Fatal error: Out of memory (allocated 26738688) (tried to allocate 4864 bytes) in /home/sites/rugbydreams.com/public_html/libraries/simplepie/simplepie.php on line 1027
I managed to sort out the others by adding a *htaccess file to the folder for each area concerned but doesn't seem to work for this one?
