When I try and install the Gravity Forms Addons (Authorize.net or PayPal), I get the FTP screen in WP, and enter my creds to download the addons, but then I get:
An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums.
I have used Gravity Forms for a year or so, for our Little League as a CONTACT form. Since I have expanded it to applications for background checks, etc.
I recently upgraded to a dev license, so that I can also use it to collect sponsorship funds from the community.
