Xpress Lister includes a default template that is 100% compliant with eBay’s 2017 Active Content changes.
If you have edited the template or created/imported your own template, then these may not be compliant.
It is your responsibility to ensure any non default templates are compliant prior to the change that is reported to be in June 2017. To get compliant you can either change to our default template (you will need a ‘clean’ (non HTML) description to do that), or edit the template yourself or engage the services of a 3rd party designer.
You can check if your template is active content compliant here.
