error display on my site

Hello @nick897,

Can you provide a screenshot of what you have in line 80 and around it in the includes/class-dco-ca-admin.php file?

I don’t see anything in the plugin code that could cause this error.

Dear Dennis, thank you very much for your reply.
According to the inspection, the code in line 80 is the same as the source code.
I am using the travel theme https://themeforest.net/item/traveler-traveltourbooking-wordpress-theme/10822683?s_rank=1, is this situation related to the theme?

Thank you again！

Nick
