Try deactivating all other plugins and switching to the default theme.
I deactivated Datepicker 2.3.2 – then I can create and save the form.
I have a date field where I would like people to select a date from a calendar – this calendar display in Chrome and Safari – but not on IE9.
I reloaded the previous version of Datepicker (2.3.1) – same issue – as soon as I activate the plugin , and save the form , I loose all the data – no form is displayed on my website.
I reverted back to a text field just to get my form working.
Any Ideas ?
Looks like Datepicker 2.3.2 is causing the problems. You could write to the developer of the Contact Form 7 Datepicker plugin or post the issue in the support forum for that plugin – http://ww.wp.xz.cn/support/plugin/contact-form-7-datepicker.
Contact Form 7 has some Datepicker support via the new HTML5 date input type (see http://contactform7.com/date-field/) but this is currently only supported on some browsers – see http://www.wufoo.com/html5/types/4-date.html
Text field may your best option at this stage.
