[Typo3] Solved: invalid result class.t3lib_db.php on line 702

[Scott Ott [ScrappleFace]]

After poring over the archives, I got a clue that my error message (see 
below) might disappear if I deleted some extensions. I killed extensions 
Ext. Repository Kickstarter, Preconfiguration of Backend Users 
<index.php?CMD%5BshowExt%5D=conf_userts&SET%5BsingleDetails%5D=info>, 
Rich Text Editor pre-configuration 
<index.php?CMD%5BshowExt%5D=rte_conf&SET%5BsingleDetails%5D=info> and 
Guestbook. The error message is gone, but I'm not sure which extension 
was causing the error. If I had to guess, I would say that the RTE was 
the culprit, since it's still in beta.

Here was the error message that appeared in the BE right pane in 'Page':

Warning: mysql_fetch_row(): supplied argument is not a valid MySQL
result resource in /PATH_TO/typo3/t3lib/class.t3lib_db.php on line 702
