Add Listing Page Blank

We are getting ready to launch our site tomorrow and we noticed if someone clicks the “Add Business” (we changed “place” to “Business”) or even a “Add Event” page when they are not logged in, instead of going to the login page a blank page appears.

Also I would like to have a menu item of “My Listings” where a user can see all of their listings for Businesses, events, and any other CPT I create. I know this is simple and can do it under Appearance => Menus; however what are the web links for a universal My Business (Place) or My Events Listings?

Final question, and I know this is a different topic, however on a Related Post Widget I see options of tags, categories, locations, ect but do not see an option of “Author”. Is there something in the coding I can do to add this option?

Finally, can you guys recommend (or do you do it yourself) for some very small minor adjustments to the plugin? I would prefer to hire someone who understands the system.

Thank you for all of your help!
