The strange thing is, this only seems to happen in the Q&A forum.

I can post a text link fine in my other forums.

Also I have no idea why my post above is now displaying in a strange box. I have tried to remove the link using remove link tool above editor  here but it fails to break the hyperlink.

I have just found that if the text that I choose to hyperlink in exactly the same as the destination URL, the display of the link is messed up.

Also, foro is adding a full stop in between the https/./ as soon as the link address is hyperlinked to the exact same destination url.

However, if my written link is change to epic.uk.com and hyperlinked to the full destination URL ( https://www.epic.uk.com/) the link displays correctly.

So to recap, if I want to hyperlink  https://www.epic.uk.com/ I cannot set the destination URL to exactly this same address. If I do, the result is as per the attachment below.

Here is how  foro is changing my hyperlink

Please explain the issue in one post to allow me follow you. I'm sorry but I didn't understand what the problem. wpForo don't add extra dot in URLs.
