What editor did you use to edit your files?

That line should probably be looking like the following:

PHP Code:

        $debughtml .= " (<a href=\"" . htmlspecialchars_uni(SCRIPTPATH) . iif(strpos(SCRIPTPATH, '?') === false, '?', '&amp;') . "tempusage=1\">Template Usage</a>) (<a href=\"" . htmlspecialchars_uni(SCRIPTPATH) . iif(strpos(SCRIPTPATH, '?') === false, '?', '&amp;') . "explain=1\">Explain</a>)<br />\n"; 


I think that if this line got changed, maybe more is wrong.

I suggest you backup this file, and try what happens if you reload the original.
