If the Add to Cart button doesn’t work, check Error Console of your browser. If there are some errors after you click the Add to cart button, follow the instructions below.
To set up the permissions, complete the steps below:
chmod -R 755 js
The command sets the 755 permissions for the js directory, its subdirectories and all the files under these directories.
The 755 permissions mean read, write and execute permissions for the user, and read and write permissions for the user group and others. Learn more about permissions in CS-Cart documentation.
If you don’t have terminal access to your server, change file access permissions with an FTP client. Most FTP clients have the Change permissions or Change mode functions that you can use to set the permissions described above. For more detailed instructions on how to set file permissions refer to your FTP client documentation.
