Getting this error message: dbModel read resource does not implement Zend_Db_Adapter_Abstract

After I put the right database connection I also changed this line:

<disable_local_modules>false</disable_local_modules>

into this

<disable_local_modules>true</disable_local_modules>

I gave recursively the 777 permission to the var folder using this command:

chmod -R 777 var

in my case

rm -rf var/cache/*

solved the issue - i changed my local.xml to a symlink though

in my case I needed just change the permissions of the var folder

chmod -R 777 var
