Hi folks; Sorry for the delay in response.
The .zip file came directly from [ redacted ] and the email stated:
Please find attached a copy of the new CardSave module for WooCommerce 2.0.2 and above. If you are not running a version of WooCommerce 2.0.2 or above, then you will need to upgrade before installing the module.
If you have an earlier version of the CardSave plugin installed, you must remove it before continuing.
To remove the plugin, login to your WordPress Admin:
a) Click Plugins > Installed plugins on the left navigation.
b) Click the "Deactivate" link below the "WooCommerce CardSave Redirect Gateway" option
c) Click the check box next to "WooCommerce CardSave Redirect Gateway"
d) Using the "Bulk Actions" drop down at the top of the page, select "Delete" and click the "Apply" button.
We also advise you check the files have been correctly deleted via FTP before proceeding.
Please see the install.txt file in the zip on how to install the module.
Please feel free to email us if you need any assistance.
I tried the uninstall options as directed above, but they didn't work. As I don't have ftp access to my site (don't ask) I asked my IT chappy to do it for me and he had a right bugger of a job getting the cardsave 1.0 file to leave. Have fun!
Hope this helps!
