If you look at the HTML source, something appears to have corrupted your links when you've carried out your edits. The same section of text is repeated multiple times so each link is way longer than it should be. The first one alone, for example, comes to about 4500 characters.

It may be fixable if you open the post editor, use ctrl-A to select everything, copy into a plain text editor like Windows Notepad that will strip out all the HTML, then paste back into the forum overwriting the old post.
