 * Hello seraphyn,
 * Please update plugin to the last version, because we added the functional, which
   prevents the appearing of these errors. If it didn’t help you, then describe 
   in more details what you done before an error occurs. Also provide the access
   to admin area, so that we can fix your problem.
 * Kind regards.
