Problem with link

[ArhZG]

I have a problem with putting a link on a page. I am getting an error.
Upon inspection, I found that the address of my website is added before the address of the link.
For example:
My website address: www.abc.com
Link to the page: www.xyz.com

When clicking on the link, it tries to connect to www.abc.com/www.xyz.com

I also tried with http:// same result

Please help.

The URL format is not correct.
You should include 'https:' in front of the address.

https://www.abc.com

If you need further assistance, then please share a DEMO project so I can see all your settings.

As I wrote, the same thing happens with https.

Apology. Now I noticed that the colon is missing
