Theme Button Layout
If you attempt to modify the layout on theme button ascx controls, Iron Speed Designer might show errors. To resolve the problem, the xml files need to be replaced.
Migration effects
ThemeButton.xml, ThemeButtonWithArrow.xml, and ThemeButtonMobile.xml are replaced during migration.
What you should do
Although the fix doesn’t affect the application runtime, re-apply any customizations you may have made to the original theme buttons.
