unfortunately I do not have the exact version number. It should be about 2 previous version before the current. I have also checked the Global permalink settings and this is set to "Post Name" which is what everything should be set as.
here is a better description of what is going on ..
So I am working with 2 servers development and production. On the development site I have first installed the event-manager plugin (from about 2 versions ago or late October/ early November). At this time the plugin installed fine and was able to configure perfectly. I was able to do a few updates and things still looked great. when it was finally time to move to production and since the databases were the same, I copied the entire site to the new server. this also included the current version of the plugin only (since you basically have to overwrite the previous version). With doing this the old version of the plugin seemed to keep the appropriate "permalink slug" (ie. /events/<title>). but when installing this on a new server as a fresh install it does not hold the "permalink slug" and defaults to "/?post_type=event&p=3952" when first creating an event. Then when the event is publish is changes to /?event=<title> instead of /events/<title>.
So far I have tried going through each of the settings of the plugin (pages and formatting) to see if there is a way to set this differently and no change made seems to work. I have also restored the production database multiple times and installed a fresh install of the plugin but it still doesn't work.
Side Note: When deleting the 3 initial events and after emptying trash they still remain on system. you have to physically delete them from the database or they will show up on the event list with a blank title with a date of 1970.
