Login Error

Hello ,

What kind of error is this , what should i do to fix it ?
Could not execute returned javascript: Cannot read property ‘addEventListener’ of null
Source: new listbox(‘XMmbJilq’,[‘SelectionChanged’,‘Shown’]);

You need to provide a lot more information than this to help figure out what is happening.

I suppose it is a Web project (do you know there is a Web channel ?)

What is the Xojo code behind that login ? Which controls ?
