Hi Ron, so looking at your moi.css, it appears to be using flexbox attributes that I think only MoI v4 supports.

Is it possible you have used a customized UI setup that was meant for v4 but you are trying to use it on v3? If it's the one from the top of this thread make sure you get the v3 version to install on v3 and don't try to install the v4 version on v3.

I also just looked at your CommandBar.htm and it also appears to be the v4 version and not the v3 version as well, also it seems to have most things removed, are you sure this is the one from the screenshot you showed and not one with additional edits ?
