Hi there,
I can tell you that all our shortcodes work as intended, so this isn’t an issue with the shortcode itself. I asked a couple questions and still need your feedback on them:
1. Can you provide the full shortcode that you are using? That will help me understand more about how you’ve configured them, which is something I cannot do from the frontend of your site.
2. You have a theme which is customizing our form markup — have you reached out to the theme author for support? It’s possible the theme is intefering with the shortcode somehow.
Additionally, perhaps there’s a plugin conflict of some sort. I’d suggest using the Health Check plugin to troubleshoot that. It will allow you to deactivate all plugins and put your site on a default theme ONLY for yourself — your live visitors will not see that. We have a write-up on that here:
https://givewp.com/documentation/resources/troubleshoot-wordpress-websites-health-check/
Then you can enable plugins one at a time and test again until you see the problem again. Then let me know which plugin caused the conflict and I can take a closer look at replicating the issue for you.
Thanks!
