We updated the plugin and now only the first day of the month is showing in the calendar grid view. Preceeding blank cells are showing, but then just the info for the 1st. No output in the calendar after that, even the cells are missing.
Confirmed on all months.
I've checked the page source, and it's not like they're hidden - the 1st is literally the last <td> present, and there's just the single <tr>.
Any pointers would be much appreciated!
