Hello, I'm reading here tips to change calendar week start day but I think there's a bug in plugin.  I have czech instance of Wordpress. In General page in Wordpress I have Monday as a week starting day. In Easy Appointments plugin setting (5. Settings / Date & Time) I have properly set calendar locale as "cs". Tried to change to de/sk/... but no change. Despite of that my calendar weeks (in backoffice) started on Sunday. On website (customer part) it is okay, weeks in your EA form are starting on Monday (= ok). Could you please check if the appropriate variable/setting/constant is called in calendar view in backoffice? Here you can find screenshots. Thanks Stepan
