Hi Gunnar,
sorry for the late response, you posted in the wrong extension forum
1.) As stated on the installation screen you need to create a Joomla menu item for the eventlist overview (this can also be hidden), else search engine friendly urls (Joomla routing) are not working correctly.
2.) Hmm seems like some CSS error, could you send me a link to the page (after you created the Joomla menu link) or notify after you created one?
3.) Did you enable booking for unregistered persons? Did you try it as a not logged in / other user? (There is a setting where you can set if organizers are allowed to book there own events) Did you set the number of available places to more then 0?
4.) Hmm in which Browser does it not show up? I tested it with Internet Explorer 8-10, Safari, Chrome, Firefox and various mobile browsers. Perhaps some CSS from your Joomla template screw it up - going to take a look at it.
5.) Which text? Could be also some CSS problems
Best regards,
Yves
P.S.: You could add me on Skype (yves.hoppe) this makes fixing CSS things much easier
