Before disabling or uninstalling extensions, disable Magento Configuration cache during the procedure, to avoid intermittent issues with the site.

To disable uRapidFlow, edit app/etc/modules/Unirgy_RapidFlow.xml and Unirgy_RapidFlowPro.xml, and change <active>true</active> to <active>false</active>.

To fully uninstall uRapidFlow, delete the following files and folders:

• app/etc/modules/Unirgy_RapidFlow.xml
• app/etc/modules/Unirgy_RapidFlowPro.xml
• app/code/community/Unirgy/RapidFlow/
• app/code/community/Unirgy/RapidFlowPro/
• app/design/adminhtml/default/default/layout/urapidflow.xml
• app/design/adminhtml/default/default/template/urapidflow/
• app/locale/en_US/Unirgy__RapidFlow.csv
• skin/adminhtml/default/default/urapidflow.js
• skin/adminhtml/default/default/urapidflow.css

Then drop DB table urapidflow_profiles
