Hi Emmanuelle,
Sorry to hear you’ve been hitting up against these issues.
when i active the view map, the category of events (selected by menu) doesn’t work : i see other categorie’s events (exemple “exposition”)
Unfortunately the current release contains a bug that may cause this. Our next maintenance release should arrive in the near future though and ought to resolve this.
I don’t find the “event.css” (located in the plugin’s /resources directory), i found other .css (event.theme.full.min.css for exemple) : the tutorial doesn’ help me
I’m not sure what you are trying to do, but if you want to add custom CSS rules in relation to The Events Calendar you should create a file called tribe-events.css and position it within a tribe-events directory inside your theme. Example:
wp-content/themes/twentytwelve/tribe-events/tribe-events.css
Then place any custom CSS in there. Does that help?
