I use WooCommerce and the EO TaxNow plugin and am on version 1.5.4. My AvaTax settings page will now not let me save anything and tax is not calculating. What do I do?
This is likely do to an expired license of EO TaxNow and being on an older version.
Login to adipietro.com and purchase a new license, which will also get you the latest version of the plugin.
If this doesn't fix your issue, we recommend upgrading to the latest version of WooCommerce.
