 * We just saw this error in our debug file whenever we use the SG Optimizer Purge
   Cache function.

 * Hello [@roberthemsing](https://wordpress.org/support/users/roberthemsing/),
 * I took the time to test the plugin using the different purge methods that are
   available, unfortunately, I am not able to recreate the issue. I have enabled
   debug mode, and the log generation feature, however, there are no entries similar
   to the one you mentioned. We are not aware of the specifics of your website setup
   in order to investigate the case further we would require access to the application.
   As the website is hosted with our company please post a new support ticket via
   the user area and our technical support team will investigate it further.
 * Best Regards,
 * Simeon Boev
