You are looking for a dollar sign in the UBBCode of one of your Graemlins:
Images & Icons => Graemlins
The dollar sign triggers the eval() function and can lead to an error message if the code contains a bad syntax. Newer versions of PHP have a much stricter syntax.
This was exactly what the problem was that I found by trial and error.
The ubbcode assigned for three of them was
burnt$
$$
$$$
I wish I would have read this first. It would have saved a lot of time.
At least this confirms it was the problem
Thank you Phillip
Issue resolved.
