Magetno problem: dbModel read resource does not implement Zend_Db_Adapter_Abstract
Posted by admin in Magento
I recived CSRF Attack Prevention message from Magento team saying that Magento admin has an vulnerability if attacker knows the admin path. Probably like most people I also used /admin/ to access the Magento administration. The message adviced to change it to something specific, so I did. And the page just crashed!?!
I got the error:
dbModel read resource does not implement Zend_Db_Adapter_Abstract
Trace:

I searched and searcher the forums and Magento pages and got some ideas on what may solve the problem. I had to contact my server provider and ask them to delete all cache (/var/cache/) and session (/var/session/) files. I couldn’t do it myself as my permission wasn’t sufficient. If that still doesn’t solve the problem ask them to restart the Apache aswell. That worked for me and the Magento shop is back and runing 
The other solution would be to reinstall Magento. Hmmmm…
Magento speed problem

Modifying, I mean uncommenting few lines in your .htaccess file can speed up your magento site a looooot. Find these lines below and just remove # before them.
