Hi jpgadbois,
Here are some things you can check if you're having an issue with a page loading in Safari:
"Reload the page
To reload a page, choose View > Reload Page, or press Command-R. If you can't reload, make sure that you're connected to the internet.
If you still can't reload:
- Press Command-Q to quit Safari. If Safari doesn't quit, press Option-Command-Esc to force Safari to quit.
- Open Safari again and try to load the page. When Safari opens, if it automatically opens pages that you don't want to open, quit Safari again, then press and hold the Shift key while opening Safari.
Check Safari extensions
If you installed any Safari extensions, make sure that they are up to date.
You can also try turning extensions off. From the menu bar in Safari, choose Safari > Settings (or Preferences). Click Extensions, then deselect the checkbox for each extension to turn it off. Learn more about Safari extensions.
Check Safari settings
The webpage might not be compatible with one or more browser settings, which you can turn on or off as needed. From the menu bar in Safari, choose Safari > Settings (or Preferences). Then click Websites, Privacy, or Security to access these settings:

We hope this helps helps.
Take care.
