Hi petrivirta,
In future please stick to one-question-per-thread. Doing so allows us to help you quickly and without confusion – and also makes it easier to offer a fair level of service to all our customers 🙂
In my language prices is in format 6€, not €6 like in this plugin. How could I change this?
We intend to make changes to support this sort of currency format in one of our upcoming maintenance releases. In the interim, please take a look at this possible workaround and see if that helps.
How I could hide end time of event from mini calendar widget and in single event display?
Our Themer’s Guide is a great reference for a basic overview of safely customizing The Events Calendar. For this specific change, adding a snippet like this one to your theme’s functions.php file would be a quick and easy way to accomplish this.
In mini calendar widget I tried to change shortened name of the month to full name. To code I changed that “M” -> “F” but then it shows nothing in the widget. What I’m doing wrong?
I’m not sure, perhaps you could share details of the change you tried (using a service like Pastebin or Gist to share code)? If I’m understanding you correctly though, you might use the tribe_events_the_mini_calendar_title filter hook to do this.
