You might want to clear the cache on your phone friend. If you've search through your phone before, it probably is remembering your site from the last visit. If you can see that your posts are being displayed in your D.B., you can click on your website to go out of your D.B. to see if they show up on your website.
I'm thinking you're using a computer to do all your postings. See if you can view your website in another browser. This will tell you if it's your phone for sure or something else. Another thing you could do is go to site manager, click on site plus, then clear cache there. That should do the trick, than just clearing the cache on your phone. All the best!

It may be a need to clear the website cache inside site manager here at WA. Sometimes the cache is slow to update for new pages but there is a button to manually clear it.

It's called caching. Your device saves a copy of your site so that it can load it faster next time around. You either need to refresh the site on your device or clear the serverside cache via SiteManager (or both) to see the changes on logged-out devices.

Hi, is your theme mobile friendly i.e. responsive. You can empty cache refresh try again or try a different browser.

You can also click details on the domain in question in site manager onward clear servers cache pale blue button.

Hi there
As Abie and AJ said below, site support here in WA does back ups of our sites. If you would like to see when it was last backed up go to Websites and select Site Manager.

Hey Suzzette
I use Updraft right now but I would like to buy the Plus when I can afford it.
Wishing you well and a terrific day..

Hi

You can back up using AIO WP Migration or Updraft plugins. UpdraftPlus is a premium and highly recommended.

Doing the Tools > Export would only save the files however not an exact duplicate copy of your site which I believe that's what you want.
