Hello to whom it may concern,

I build websites in Hostinger through their web builder and when I try to embed a form on my site or a calendar on my site it gives me a 500 Server error within the embedded code section.

I spent hours working to find a solution and there seems to be an issue between Hostingers sandboxing and your iframe embedding need an external connection. I am desperately looking for a solution andy guidance or help would be greatly appreciated.
