OK - you're editing the language file - wrong file. Remove that stuff from the language file. Edit the showprofile.php script (in the ubbthreads directory).
Somewhere near the top of the script, you'll have a line like this:
<br />$html = new html;<br />
AFTER that, Paste this:
<br />// Block them if they aren't logged in.<br />if (!$thisuser['U_Username']) {<br />$html -> not_right ("You must be logged in to view profiles.",$Cat);<br />} That should do it.
