I’m sorry you feel that way @hetjou.
There is nothing wrong with the recent version of WPCasa. Exactly the opposite is the case. WPCasa had some security issues which was the reason for the plugin review team to close the plugin at www.remarpro.com. I’ve been working hard to bring WPCasa back and make it available to the public again. This includes closing the security issues. Normally a user should be grateful instead of blaming me for something not working.
The problem is not WPCasa but how Ninja Forms works and the way that you insert the contact form as a shortcode in the description. Just because it worked so far doesn’t mean it was right. I have closed the security gap and explained two ways you can solve your problem. If you can’t do it yourself, I ask you to ask a friend to help you. I don’t have time to make this customization for you at the moment. I invest my time in the plugin and make it available for free. You are free to use it as it is or customize it your self.
A third option would be to use another contact plugin that does not use its own HTML tags (which causes the problems). You don’t have to write code for this. You just have to test it.
I have taken up your case and will try to make the whole thing more compatible in the future. But right now I have other priorities.
