We have a DNN 6.2.8 site, with Events calendar 5.2.3.  We haven't used Events much recently but we revived it, and now we can't find how to add a new Location.  The location dropdown shows locations we used in the past, but even logged in as host we can't add a new location to the list.  What are we missing?  I've looked through the FAQs and the documentation and I can't find anything about adding a new location.

Thanks for the reply.  Since we definitely don't have an item on the action menu, we obviously have either a skin/container problem, or a jQuery problem, or both.  Is the issue with a version of jQuery, or with the interaction between jQuery and and the skin or whatever?  We're using a commercial skin, In Skin – Light Purple color variant from Cyberspace Solutions, if that rings any bells.  

We have a set of menus reached through the Edit Settings icon:  General, Look & Feel, Detail View, etc. - all the items mentioned in the online documentation I was reviewing.  There is a much smaller set of menus reached by the gear icon.  There is nothing in either set of menus about adding a new location, or even managing the list of locations.  When we edit or create a new event, there is a Location dropdown, but there's no way to indicate anything that isn't already there.  I suspect there's a database table somewhere that we no longer have tools to update.  

Now you mention categories, I realize that we don't seem to have a way to add a new category, either, although we have some existing categories that I know I added.
