shyine19 Posted May 4, 2012 Share Posted May 4, 2012 (edited) Hello, I just installed the AvaTax module and when I went to my shop it would not allow me to put any item in the cart and gave me a message saying I was unable to add to the cart: TECHNICAL ERROR: unable to add the product. Details: Error thrown: [object XMLHttpRequest] Text status: error I then uninstalled it, and reinstalled it and the second error message appeared : The module was successfully installed but the following file(s) already exist. Please, merge file(s) manually. /override/classes/Tax.php /override/controllers/AddressController.php /override/controllers/AuthController.php Any thoughts on how to merge the files and on what happened? Thank you Edited May 4, 2012 by shyine19 (see edit history) Link to comment Share on other sites More sharing options...
Mike Kranzler Posted May 4, 2012 Share Posted May 4, 2012 Hi shyine, You should be able to do this very easily by accessing the paths listed in that second error message via FTP. I hope this helps. -Mike Link to comment Share on other sites More sharing options...
