Getting "Page Can't Be Displayed" Errors

Any page or specific pages?

Are you using any Cache plugin? If so, clear cache.

Could also try resetting your Permalinks at Dashboard>Settings>Permalinks.

Generally it’s the home page. I have cleared the caches several times.

I do not see a reset option under the Permalinks settings.

It’s really sporadic from what I can tell so it’s unclear to me it the new theme is causing it.

Assuming you’re set to Default or Post name, choose one of the other settings, Save, then reset back to Post name and Save again

I called my hosting provider and they confirmed the issues are with them.
