Wordpress page not found in Chrome, Safari

Question

I just moved my wordpress site to a new domain name and I am getting a "page not found" error for a couple of pages, but only in Chrome and Safari. It was working before I moved it. I can still see the page in Firefox, when I have copy and paste the same address into Chrome and I still get "page not found". This happens on 2 pages only. I've tried disabling any non-essential plugins and it didn't make any difference.

Here is one of the pages not working - https://nemanjabogunovic.com/timeless-classics-sheet-music/

And here are some of the headers:

Answer 1

can you try changing the permalinks back and forth? Do this under settings > permalinks, swap to another setting, save, swap back. (Sometimes permalinks get stuck, and need to be refreshed.)

If you are using any plugins to cache your site, or make it run faster, try disabling them and checking the pages.

Try going to the page in question backend, and following the permalink from there, is it displaying when you do this?

Answer 2

You're right, I just checked and noticed that page gives me a 404 error and I've never visited before. Not a client-side caching issue at least.

Seems odd because it is a real post in WordPress - when I do a search 2 pages for the "Timeless Classics" page show up - https://nemanjabogunovic.com/?s=timeless

The one that doesn't work has this URL - https://nemanjabogunovic.com/timeless-classics-sheet-music/

Just checking this isn't the correct one instead? https://nemanjabogunovic.com/products-page/sheet-music-timeless-classics/timeless-classics-downloadable-e-book/

Answer 3

So this didn't really solve the mystery as to why it was happening, but I resolved the problem. I ended up changing the post link by adding -tab to the end and it's working now. Wish I thought of that sooner, would have saved me some trouble, but still a bit curious what was going on.
