Can you give me (super) admin and (s)ftp access so I can take a look?
And tell me on what url I can see/reproduce the issue.
You can use the 'Confidential information' button in the forum editor to hide sensitive information.
Like said in the other thread, it seems like those fields are not being output through Articles Field.
You can see that the URLs are correct and spaces are not added on that test url you gave:
So it seems this is down to something else you have locally.
