[TYPO3] PHP Fatal Error ...

[Peter Geldhof]

Does anybody know how I can work arround the following :

(Extract from my web server log) :

[client 192.168.68.254] PHP Fatal error:  Class 't3lib_htmlmail' not 
found in /var/www/www.nomadisk.com/t3lib/class.t3lib_div.php on line 
3500, referer: http://gimli.nomadisk.com/index.php?id=28

Is invoked when I try to send a HTML mail with the tip-a-friend extension.

A file called "class.t3lib_htmlmail.php" exists in my t3lib/ dir ...

Many thanks,
Peter
