Hi @sp691,
Thank you for providing that information.
I was able to add the form to a demo page and could see it working properly. Here is my demo page: https://jsolofree.tk/contact/
Checking your page, the reason the form is not displaying is because inline styling is being applied to the form as shown here:https://snipboard.io/9F10jM.jpg
Make sure to check if there are any styling that is being added either by your theme or a possible plugin. You can also try running a conflict test to see if there is a possible configuration conflicting with Forminator. First, create a recent backup in case you lose any settings during the test and have to restore to a previous working state.
Then deactivate all plugins and MU-plugins apart from Forminator, activate a default theme like TwentyTwentyOne, clear all caches and check again if the issue is still there. If not, it means that something is conflicting, so start activating the remaining plugins and theme, one by one this time, checking every time for the reported issue, until you reproduce the issue, thus finding the conflicted combination. The following flowchart image can assist you during this test: https://premium.wpmudev.org/wp-content/uploads/2015/09/Support-Process-Support-Process.gif
