Notice undefined index

Hi @skurrilewelt thank you for reporting, I’ll improve the code in the next release. But for the error to be happening, there might be something off, like a setting missing or something similar. If you share the link to the page where this happens I can also take a look.
Greetings, Carlos

Okay, this is only a warning, now I’ve got another error, and this breaks the whole site (javascript):
jquery.min.js:2 Uncaught Error: type property can’t be changed
at Function.error (jquery.min.js:2)
at Object.set (jquery.min.js:2)
at attr (jquery.min.js:2)
at Function.access (jquery.min.js:2)
at init.attr (jquery.min.js:2)
at dtp_init (dtpicker.js?ver=5.2.2:213)
at HTMLDocument.<anonymous> (dtpicker.js?ver=5.2.2:3)
at l (jquery.min.js:2)
at Object.fireWith [as resolveWith] (jquery.min.js:2)
at Function.ready (jquery.min.js:2)

Because it’s not allowed to change the type attribute of input fields and btw. this won’t work in IE either – or I’m wrong?

The concerning page is behind a directory password, because it is not live yet. I can give you credentials and link via mail or?

Great support, btw.

I forget to add the trace for the first issue:

Maybe it helps?

Thank you for reporting @skurrilewelt and I’m sorry for this issue.
Unfortunately at the moment I am not supporting IE.
But if that error is happening on other browsers, I will look into it. I can’t reproduce the error, so if you could share more details and the link it would be great.
