Hey @Starmaxtransport,
First, I’d like to let you know that we do not bundle plugins that don’t work. Before releasing, every plugin is extensively tested. Though bugs are inevitable, it is not to the point that the software in general becomes unusable. If it does not work on your end and works for thousands of users, it is almost always an issue within your overall system including the combination of plugins used, optimization, server setup, etc…
Your case is not a bug. I inserted the only E&P form you have in a test page I created in your site and it works (see secure note). I tested the form from beginning to the end.
And, though you can put an E&P form in a lightbox, that is not recommended. It is not its intended design both technically and UX-wise to be placed in a modal or lightbox.
You say it doesn’t work on your end. Would you mind giving us the specific page or URL? Please also check your site of any malicious code because I was redirected to another site visiting your other pages.
Also, clear all caches including your browser cache then disable your caching plugin because it could be that your seeing a cached page.
Thanks.
