 * I tried this, but my thumbnails still aren’t displaying and I get an error message
   if I try to edit or re-generate them. All sorts of errors:

 * I tried deactivating all plugins and re-enabling them, but did not help. I get
   no thumbnails to display and I cant edit them or regenerate the thumbails. I 
   get a failure ‘exceed memory limit’ for each one.
