I just upgraded from 4.5.3 to 5.6.2.  It took 1 week of nights, but finally everything upgraded/ installed "successfully".  It would have been much quicker except I had difficulty with hosting service tools.
Everything I have checked so far seems to be working okay (except I cannot update/ add modules), but I am getting a long, distracting message on every page.  Can you help me get rid of it?
