Hello, Teralt2003,
Thank you for your response.
You mentioned that the problem occurs after cache plugin activation, and the theme works fine without it. Other of our customers use cache plugins and did not send reports about such problems.
Have you tried to contact support of cache plugin you are using? Please do this, and let us know their answer (probably one of the plugin options needs to be disabled to solve this, if they reply that changes should be done from our theme side we also need to know it).
Thank you for your cooperation and we look forward to hearing from you soon.
Kind Regards,
8theme team
