Zeirys Posted January 31, 2014 Share Posted January 31, 2014 (edited) I have this issue installing avalara module which is stopping me from starting my store. Everytime I try to install the module I am greeting with this error message : The following module(s) were not installed properly:- avalaratax : Unable to install override: The method getOrderShippingCost in the class Cart is already overriden.Does anyone know how to fix this? It is really stopping me from starting my online store which was supposed to be started yesterday, I am not very computer bright either unfortunately. Issue has been solved with a clean install of prestashop. Now my Avalara is not calculating sales tax although I am a registered Avalara member, and have put in all my information correctly as a specialist from Avalara has helped me set it up. Any idea what might be the problem and how to fix this? Edited February 3, 2014 by Zeirys (see edit history) Link to comment Share on other sites More sharing options...
Dh42 Posted January 31, 2014 Share Posted January 31, 2014 What module are you using that has overrided the class? Is it compatible with avalara? Link to comment Share on other sites More sharing options...

vekia Posted February 3, 2014 Share Posted February 3, 2014 hello you use some other module which overrides this class in prestashop it's impossible to override the same class/controller from two different modules you use some other non-default solution? (instead of this Avalara addon) Link to comment Share on other sites More sharing options...
