Hello There,
Thank you for providing the information. We have investigated and it seems that there is a JS error on the page. This could be the reason why it is not showing on the page. The error could be caused by a 3rd party plugin. You could try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
Another this is that, I noticed that you have installed w3 Total Cache. Please keep in mind that after doing every updates and small site changes such as saving your convertplus slide in, always remember to clear all caches when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors. Caching plugins are best enabled when you are already finish developing your site.
If still nothing is working, please pause your slide in and create a new and see how it goes.
Hope this helps.
