Not sure if I'm overlooking something here but I am only getting a single result when using rwmb_meta to retrieve values for a checkbox list field. You will be able to see from the screenshot that there are two matching the post in question (#768). What am I doing wrong??
Morning Long and thanks for staying with this. Very strange events here...I tried a few debugging options including resorting to default themes, trying different versions of MB and re-coding the function initialising the metaboxes, all with not joy. I then put it all back as it was and suddenly I am getting the desired array returned. I have no idea what happened here...but it is seemingly all working properly now.
