WB21 - error in Chrome - clWDUtil.pfGetTraitement is not a function

Hi,

One of my sites is working properly in Edge and Firefox, but not in Chrome. Very simple site wth just a login+password field and a login-button. After pressing the button a login check is done and accordingly the next page is shown.
owrks in Edge and Firefox, but in Chrome nothing happens.

When I open the debug-F12 window in Chrome I see the foloowing error
Uncaught TypeError: clWDUtil.pfGetTraitement is not a function at <anonymous>:1:10

What can be wrong?

I'm using the 10 connection version 30A210067f
