Hello All,
I am trying to install this JD builder plugin from upload package file option but it is not getting installed and gives Error 404. sharing the screenshot below.
Somebody please help me out.

Hi,

This is a frontend error, but are you getting any backend error like is the file not installing or something wrong with the file? If so then please share a screenshot of that and share the file you are installing.
Frontend error can be resolved if you correct the menu type of this page.
Also since you have created 2 posts with the same issue I'll delete the other query.

Thanks,
Nishtha
