My site stringloveguitar.com is behaving strangely.
On my computer, everything looks fine. On my girlfriend's computer, however, some of the pages (primarily the Store page) only display an old version of the page (I updated that page last spring, and she still sees the old version when she visits the page on her computer).
Additionally, on that old Store page that she sees, the Nav Menu is also the old version of the Nav Menu from before last spring. And then, as I click around the site on her computer, the Nav Menu displays its current version on some pages and the outdated version on other pages.
Just now, I navigated directly to stringloveguitar.com/store and the old version of the page displayed. But after I clicked into the Store page from a different page on the site, it is now displaying the current updated version.
What's going on? I have no idea where to start to figure out why this glitch might be happening. Anybody have any experience with this kind of thing?
Your help is very much appreciated.
