    Advanced Designer: Changes made in the designer tool are not being applied.

    Asked by incharged on November 11, 2016 at 04:52 PM

    When I click the Design button and make changes from the menu on the right, it works fine. But when I click on the Advanced Designer button and make changes from there, nothing works and my changes do not save.

    What changes are you trying to  make in the designer? I cannot replicate this, but I think you are experiencing some error in the designer. Please check your browser console to see if there's one:

    I'm just trying to make general changes; colors, fonts, etc. It looks like I am getting some errors. Do you know what it means?

    I have checked your form in the designer tool and I was able to replicate the same problem, I have also cloned your form and the same problem happened in the cloned form, I can see there are some messages displayed in the web console at the moment that changes are made to the form.

    I will forward this thread to our second level so our developers will investigate and resolve the problem, we will let you know as soon as we get updates regarding this thread.
