[Typo3-dev] What's that? "mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource"

[Michael Vogel]

Hi!

When calling the page
<http://www.dabo.in-berlin.de/gandalf/dokumentation.html> i get the 
following error:

"Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL 
result resource in 
/var/lib/typo3/typo3_src-3.7.0/t3lib/class.t3lib_db.php on line 723"

I'm working with a very customized version of RealURL. (Downloadable at 
<http://dabo.in-berlin.de/temp/class.tx_realurl_dummy.php.gz>) I took 
"class.tx_realurl_dummy.php" and modified it to enable it to use the 
field "Speaking url Path Segment" for the whole path.

Its working like a charm - but on some pages I get the error I mentioned 
above.

Can anyone help me?

Thx!

Michael
