It seems there is an Issue with the Zend_Cache
is the Cache limit set to small to get magento running?

please help me solve the problem, i'd love to get my site up and running soon

thank you very much

is there a Zendserver Setup on Altervista?

maybe this is the Problem?

s5scooters:

is there a Zendserver Setup on Altervista?

No, it is currently unavailable, however you should be able to install Magento anyway

yes I was able to install it, but it'S not working properly

when will it be available again?

thank you very much

[Gianluca]

I guess you can just disable Zend Cache support to have it work.

no it's disabed in database, but still same error on all admin pages

ok I modified the script and now it works
