[TYPO3-install] unsynchronized extension list - very strange problem

[Jakub Tesinsky]

I use typo3 on more domains and I found VERY STRANGE problem today. When 
i login to backend from different domains I have DIFFERENT list of 
extensions installed, thought there is only one installation and the 
other one is just symlinked.


Details:


I have installed typo3 on domain1.com normally. Then I have symlinked 
the whole installation to domain2.com.

The error is: When I use domain1.com/typo3/ backend I see DBAL and other 
extensions installed, BUT when I use domain2.com/typo3/ then I don't see 
them.

THIS IS VERY SCARY! Should I always control all subdomains to make sure 
that all extensions are synchrnoized? How it is really possible - I 
thought that the list of installed extensions is derived on directories 
in the ext/ folder - and these two domains are just symlinked thris 
should me the same.

Or my installation is flawed?

Any ideas.
