Again, running Chrome on Mac (High Sierra 10.13.6), I do not use other browsers (nor will I because everything I do communicates/saves/infaces best through Chrome). My cache and cookies have been cleared very recently. I use the "Spring" theme. No specific forum. It's the same throughout. Works fine on iPad and iPhone. It's pretty specific to my laptop.

So far today, it is running more smoothly. We'll see.
