Hi,
Unfortunately, but it is what it is. If the template works on your website, exactly how it works on our Live Demo; our free-support ends there. Custom coding modifications are not supported by free-support. Because "sky is the limit".
FYI: You can disable the "QuickLook" functionality that comes with the CleanMart via "Flexible VM3 Template" plugin parameters.
If you are using a 3rd party plugin to add your own "quickLook" functionality. You should better contact to the developer of that plugin. They must provide you support or guidance about installing the plugin. Because this is their plugin and they can easily implement it to any 3rd party VM Template (in your case, CleanMart)
For example; we provide "free-installation" service for our "Flexible Zoom Effect" plugin. Installing VM extensions (plugins) can be tricky sometimes; especially on top of a 3rd party VM Templates.
Regards.
Support
