All styles had todays date and time stamp
I was stupid to delete the one I believed was old. The only thing different i found was in
CP> Styles> styles settings >Name, Images & Wrapper > General images
one read Ventura the other Default_Dark
I guessed it would have been me in the past changing to Default_Dark
That one was it that I deleted and I hope and think it was the correct file.
The little red flag was feedback Gizmo but I thank you for the string.
I have tested the Youtube inline link. Fantastic.
