Hello,
Please also do a compatibility test. I assume that iframe embed is working because it loads the form after the page has loaded, thus decreasing load on your server.
- Please deactivate all your plugins except our plugin.
- Check to see if the problem is gone.
- If the problem is gone then please activate your plugins one by one to identify the culprit.
- Otherwise, please switch to a default theme and see the problem is still there.
If the methods above failed, then please let me know.
If you want to appreciate my efforts, then please rate our products. It helps us establish stronger reputation across the marketplace.
