TYPO3 Core

I took a new install of 6.2.14. Every was working out of the box. No changes to configuration, and then installed the "Official Introduction Package". It seemed to install ok. the backend worked for all the pages, except when I went back to the Extension Manager. The page was just blank.

I was able to reproduce this every time.
I added some debug and finally got an error when loading the Extension Manager about not able to find the "rtehtmlarea" extension.

I went thru the typo3conf/PackageStates.php file after the install and the "rtehtmlarea" extension is in the file, active and same exact parameters as the file before the install.

The only real difference between the original PackageStates.php and the version after the package install is that the order of the array is reversed. Not sure if this matters.

Just to see if anything else could be the problem, I replaced the LocalConfiguration.php and PackageStates.php with the original files before the install, and I was able to get into the Extension Manager. I could not leave it like this, because the DB obviously had updates and new tables. But I think it seems to point to something in the files that the system does not like.

I have attached the orig and version after the package install.
