Cashing Problem? Site sometimes (!) doesn't refresh properly

Hello,

I have an issue, that I think is related to cashing but I am not sure. I use a dynamic page and added buttons to switch from one dynamic subpage to the next and back. First I noticed that sometimes (!) the gallery which exists on every site does not refresh. Other items do. The gallery in these cases does so only when I refresh the page manually. I noticed later that I have the same problem with buttons that I added to lead the user to different sites (fixed and dynamic ones) on the page: While working on the site I changed their destination and now my browser seems to remember the old destination, even though I did publish a new version.

Naturally I deactivated the cashing for the dynamic page. But this does not seem to take any effect. What else I tried:

  • deleting all browser data
  • using incognito tab
  • using different devices (2 phones, several laptops) and browsers (chrome, brave, firefox)

This really confuses me and appears to be a bug? Notice that it does not happen all the time but often enough.

Any ideas on what else I could try?

Thanks in advance!
