Thread:Extension talk:Semantic Forms Inputs/Datepicker error: Undefined offset: -1 in ... /extensions/SemanticFormsInputs/includes/SFI DatePicker.php on line 287

Hello,

I get this datepicker error on two wikis, running on 1.23.1 /SFI 0.9.0 alpha and 1.23.6 / SFI 0.7.


 * Undefined offset: 0 in [...]/extensions/SemanticFormsInputs/includes/SFI_DatePicker.php on line 283
 * Undefined offset: -1 in [...]/extensions/SemanticFormsInputs/includes/SFI_DatePicker.php on line 287

The corresponding lines in the PHP file are about the minDate and maxDate.

I can acces, fill in and save the form, but would quite like to get rid of the error message. I have taken out the "data format" part, but with no effect. Any ideas what I could do to fix this error?
