There are more Bugfixes for j2Mantis. Thanks to Alex for sending me a patch and make the JS work in IE.
Sorry there was a problem with the captcha-Plugin. Maybe in the next version I’ll find a better solution to include the plgSystemJCCReCaptcha so that j2Mantis will work without installation of the JCCReCaptcha Plugin.The next big step will be to be able to set up options related to the log-in user in Joomla. I have no timeplan for this. If you have any other wishes, please tell me.
