How To Do a Browser Refresh
When we do updates to your website you might not see them properly or even at all, but new visitors will.

This is because web browsers keep their own copies of web pages on your computer, in what's called a cache. It makes pages load faster, but it doesn't always show the latest images (particularly if the image files have the same name as before) or stylesheet classes. So we need to do a hard/forced refresh.
Microsoft Edge and Firefox
Hold down Ctrl then press F5, on a Mac it's Cmd and F5.
Press and hold Ctrl then Shift then R all together. Same on a Mac but Cmd instead of Ctrl.
You need to empty the cache first by pressing Opt + Cmd + E, then do a normal refresh or press Cmd + R
