If you get an error like:
Fatal error: Call to a member function select() on a non-object in /home/username/public_html/app/code/community/Fishpig/Wordpress/Model/Resource/Page.php on line 119

Then, check you’ve not just changed a MySQL username, without updating the fishpig configuration, or otherwise Fishpig can’t access the MySQL database for some reason. It seems to store a MySQL login in Magento config. I’ve not yet found exactly where, I’ll update this post with more once I understand more about what it’s doing.

It presented as the main Magento site throwing the following error:

exception ‘Zend_Exception’ with message ‘dbModel read resource does not implement Zend_Db_Adapter_Abstract’

Which it seems that most everyone will tell you to clear your cache to fix. You *will* need to clear your cache, probably. Just, after fixing the MySQL connection issue.

The following line is to make it easier for people googling to find this post:
Fatal error: Call to a member function select() on a non-object in /public_html/app/code/community/Fishpig/Wordpress/Model/Resource/Page.php on line 119 magento fishpig

This post my making sure  https://xkcd.com/979/ doesn’t happen from me.
