problems loading video embed code - Solved

When I load a video code in the corresponding template, when loading the data of a property, after saving, the page is forbidden and there is a message that says: "You don't have permission to access this resource."
Please help. I hope this is the correct topic.
Thank you.

Hi Victor,
The issue has cause from your hosting doesn't allow to submit the form with HTML code. It relates to mod_security of hosting, please contact with hosting admin to ask them to adjust server configuration to allow the form with HTML code to be submitted
Thanks
