In order to add an image for the Page Title Background in the Events listing pages, please follow the steps below:
Example for listing pages:
http://church-event.vamtam.com/events/map/ (available with Event Calendar Pro)
The listing pages are automatically generated from the Event Calendar plugin and they don't have local Vamtam options like the standard ones. They use the default theme's options.
Please go to the global VamTam option panel in Dashboard > Vamtam > Styles > Header > Page Title Background
Click the "Save changes" button
