I cannot access the administrator area as of this moment. This is the error I'm getting: Fatal error: Cannot redeclare hikashop_product_price_for_quantity_in_cart() (previously declared in /home/public_html/plugins/system/custom_quantity_tax/custom_quantity_tax.php:122) in /home/public_html/plugins/system/custom_price/custom_price.php on line 31 I'm currently using the JAT3 framework, the latest version of Joomla, and have several plugins installed. Any help on this matter or input would be appreciated. Thanks!

You can't use both custom price and custom quantity tax plugins together as they use the same override.
