[TYPO3-english] Caching problems

[Martin Lipp]

Hi,

i've got some problems with caching after updating quite a big site from 
4.5 to 6.2. For example after clearing the system cache or executing the 
crawler from command line the site breaks with an error (open-basedir 
restriction in effect), because TYPO3 tries to read files from 
'/home/user/home/user/typo3...' instead of '/home/user/typo3...'. In the 
directory 'typo3temp/Cache' are always files that have contents with 
'/home/user/home/user' in it.

Where is this coming from? Has anybody an idea of how to might fix this 
problem?

Martin
