Have just spoken to the hosting provider and they have looked at the site and increased my php4.ini as well and the site still has the problem!
I am not sure what to do now?
Unfortunately it has not made any difference. I can only view the html editor window and not the visual window. I used the method described in the tutorial you sent and increased the memory to 64M in wp-config.php.
In the editor window (beside the Add Media button) there is a down arrow and when i click i get this message…
