 * Hello, [@wxfc1](https://wordpress.org/support/users/wxfc1/)
    Thank you for contacting
   us! As we can see this issue with cache. Try to deactivate and update plugin 
   to latest version. After that pls check results. It would also be helpful if 
   you provide a php log for this time for diagnostic purposes.
 * Wishes,
    Ole
