Hi Joe,
I was able to see the problem by stepping through the code. The Subscribe control is apparently inheriting Visible="false" from its parent container divRight, though divRight is being set to visible it is happening after the page load event fires in the Subscribe control where we have
if (!Visible) { return; }
so it is not loading the settings.
I was able to workaround it by setting AlwaysShowRightColumn="true" on <portal:StyleSheetCombiner so that divRight is set to visible earlier in the page lifecycle. Is that a workable solution for you?
I will remove the code shown above from Subscribe for the next release, I did not realise it would inherit that form a parent control.
Best,
Joe
