Does not accept the reported URL

Good afternoon!
First I wanted to apologize for the way I’m writing.
I’m using Google Translate to help me in this text.
I have the same problem.
I put the URL and saved, but the URL remains incomplete, not pointing to the correct page.
I also change some features such as: open in the same window, do not sample the title or description, description character limit and image height ….. but also not working.

Related to URL, I figured the problem was the number of characters, so I entered the code in the init.php file and increased the VARCHAR url number, but it also did not change anything.

Can someone help me, because I really liked the plugin!
I want to thank you for your attention!
