Hi achmarketing,
Thanks for reaching out!
I cannot see your current submission page as it is password protected.
The community submission form uses the default events template itself.
You can create an override for this template in your own theme by creating a file at
[your-theme]/tribe-events/community/default-placeholder.php
You can find further information on template overrides in our Themer’s Guide – https://theeventscalendar.com/knowledgebase/themers-guide/
Hope this helps you get started. Let me know if you need further help.
Cheers,
Andras
