RE: I hope this gets figured out because I plan to use this theme from now on
I doubt this is a conflict with the theme as the theme should not be doing the redirect. Generally this is handled in your .htaccess file. Seeing as Connections is somehow having an effect… how do you have this redirect setup? Are you using a plugin or is there actually a setting in Vantage to handle the redirect? If it is either, I very highly recommend using the .htaccess method. Using a plugin or theme option to do so is adding additional page load time because WP has to load twice in order to do the redirect. Basically this means your site has to load twice to show the page once. Using the .htaccess, WP is never loaded since the redirect is handled by the server and not WordPress.
That said…
I would like to investigate why having Connections activate makes a difference because as mentioned there is no code in Connections which cares about or should affect this type of redirect.
I did notice that this affects only the front page … no others. So that does provide a clue.
If you can give me a WP admin login and FTP login I can investigate further. The details can be posted here as a private reply.
RE: When I deactivate Connections the Warning for Leaflet Maps Marker disappears but, when I reactivate Connections it appears again.
You can ignore this message. Leaflet Maps Marker and Connections works correctly together. Leaflet Maps Marker is simply detecting Connections usage of the API and displaying you a warning that they might be conflicts.
