i am facing a situation where i can't find any solution. My website was working fine till i installed a new extension. After installing this extension my website and admin panel is not working. Actually i have installed lower version extension because i didn't noticed version and installed.
I am getting this stack trace :-
dbModel read resource does not implement Zend_Db_Adapter_Abstract

I have done all the solution but no one is working. i have searched over google and searched on stackoverflow also. But no solution is working.
If you are sure the extension created the problem. You need to disable the extension and try again.
For this you need to follow these steps
app/etc/modules/
.Ksv_Attributemanager.xml
there. Open that file.<active>true</active>
. Put false
there.Let me know whether it makes any difference.
If you didn't find such file, then any one in those file is contributed by that extension. What you need to do is, open all files which does not start with Mage
, and check for this code.
<config>
<modules>
<Ksv_Attributemanager>
<active>true</active>
<codePool>community</codePool>
</Ksv_Attributemanager>
</modules>
</config>
There may be a depend
node present along with this one. If you find such code in any one of the file, put false instead true
and try again. (If this code present, that means that file is a part of that custom extension)
