I have tried to replace kadira with ostrio (suggested by the docs) in this template - https://wrapbootstrap.com/theme/angle-bootstrap-admin-template-WB04HF123
but it showed no error, just blank page instead of template with all the widgets.
It is difficult to debug something when there are no errors (
Is ostrio flow router extra fully compatible with kadira or there are some peculiarities, which require some tweaking during replacement?
Also, what could go wrong when you see blank page? What is the best way to debug such situations?
