Hi there! I've been trying to solve this, but I'm not much with php so I thought I'd reach out. We are using the calendar from Modern Tribe (The Events Calendar) and we are unable to select a single column template as it causes an error. I've tested on many other themes and it works, so it seems to be a conflict within Graphene I think?
This is the error message I receive when I try to select any of the pre-built templates in the Calendar options.
ERROR: You must supply the post ID to get the image from as an argument when calling the graphene_get_post_image() function.
I'm not sure what to do with this, but I would really like to solve it so I can have a wider calendar on the site and still use the two side bars on the rest.
Any assistance is GREATLY appreciated!
