Has anyone managed to get this running and working with the responsive_classic template?

Have tried on both version 1.5.8a and 2.1.0, and everytime, this plugin causes the product page, and the right hand column of the website to vanish. Just the product title stays.

Also, tried the Lightbox plugin as well, and the same thing happened.

No errors in the logs either.

I know the plugin isn't supported anymore, and hasn't been updated for some while, but after reading through this forum, it seems like some people have been successful, and managed to get this old plugin up and running.

Any help or suggestions, on what might be causing this not to work with the responsive_classic template, would be very much appreciated.

Running on PHP 8.2

Kind Regards,

Andy
