I have Sendy installed at http://www.mydomain.com/sandy/ (not my real domain). When I login, I see a redirection to http://mydomain.com/sandy/ which then redirects me back to http://www.mydomain.com/sandy/login, prompting me to login again. This cycle will repeat indefinitely.
After the first login attempt, manually entering the URL http://www.mydomain.com/sandy/ will get me to the main dashboard screen, correctly logged in. Thereafter, everything works fine. I presume this is because my license file is showing as registered to mydomain.com rather than www.mydomain.com.
(I see the same behaviour if I login using http://mydomain.com/sandy/login.)
I've checked my .htaccess rules and can't see anything that would rewrite the base URL to include a www prefix, so I guess this is being done by Sandy itself? Do I just need a new license key that includes the www prefix, or is there a more straight forward fix I can apply, to avoid this two-step login?
