Hi all,
a GPXTrackMap user just informed me that he was not able to create an account here in the forum, because the ReCaptcha at the bottom of the registration page did not show up.
After some googling (how ironic!), it seems that Google had changed the URL for their ReCaptcha service, and Joomla's ReCaptcha plugin still pointed to the old URL.
I have fixed this now(*), so anyone who tried to register here should now try again, please - sorry for the inconvenience!
(*) the "fix" was to modify a CONST in the plugin code as described here:
Joomla ReCaptcha plugin fix
cheers, Frank
