thanks a lot for the video guide.
I think the issue is that there is something of corrupt into my wordpress installation.
I tried many times to delete the plugin and to clean the cache with W3 Total Cache plugin but when i install wp datepicker again, I will find the some configuration done by me last time (same language and same selectors).
I tried to analyze my database in order to understand where these dare are saved but I didn’t find anything.
Can you please indicate which wordpress table create/use the plugin?
Furthermore the arrows images are located correctly in directory.
thank you.
