Fatal error after updating

Hello, I just updated to HikaShop Business version 1.6.0 and am now receiving a fatal error both in the front end and back end of my website. 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!

Hi,

Rename one of the two files and the error won't happen.

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

Thank you for the fast reply, that fixed it.
