Page layout may be unexpected due to Quirks Mode

[WarlisonAbreu]

Hello, Brian, I am Warlison from Brazil. I acquired the license for Smart-Connections yesterday. First, I have to congratulate you on your work. From the brief moment I had experimenting with the plugin, I can say that we are at the beginning of something that has the potential to be more than just a plugin, and I already feel like I can't live without it, haha. You can count on my support.

I need help because when I access the program, it presents the following error:

"One or more documents in this page is in Quirks Mode, which will render the affected document(s) with quirks incompatible with the current HTML and CSS specifications. Quirks Mode exists mostly due to historical reasons. If this is not intentional, you can add or modify the DOCTYPE to be to render the page in No Quirks Mode."

If you could help me, I would be grateful.
