Register_XH facilitates to restrict access to certain CMSimple pages to registered users. Therefore it has a simple user and group management as well as a login form, with the optional possibility for visitors to register per email. It is used by some other plugins to add user management (e.g. Chat_XH and Forum_XH).
Register was developed in 2007 by Carsten Heinelt based on Michael Svarrer's Memberpages plugin.. In 2010 he gave permission to Gert Ebersbach to adapt it to CMSimple_XH and to further improve it. The plugin was then distributed as Register_mod_XH. In 2012 Gert Ebersbach discontinued the developement, and gave me the permission to maintain and distribute the plugin. Many thanks to Carsten Heinelt and Gert Ebersbach for their good work and the permission to further maintain the plugin!
Since 1.4pl1 and 1.5beta3 the password hashing algorithm has changed, so your users old passwords won't work anymore.
If you have already installed version 1.5rc1, you can download and install the patch. This won't overwrite any data, config, language or css files.
