Updating frevvo with wrong license key for multiple times can cause the following License Warning:
Unable to renew license for 0 attempt(s). Your license will expire in 0 day(s). Please contact frevvo for help.
This issue can be fixed by restarting Frevvo server. Adeptia restart would reset the Frevvo server. Once the services are started then apply the Frevvo License.
Note: In order to access RichForms from a secure server (HTTPS) you need to modify the following property in the server-configure.properties present under AdeptiaDirectory\\AdeptiaServer\ServerKernel\etc :
abpm.frevvo.httpScheme from HTTP to HTTPS
