A forum I go to (Linux mint forums) will not show updated posts on the index page until I either click on one of the categories, then click on the index page, or sign in.
I've tried it with my computer (Linux Mint) and my wife's (I Mac) on both Ethernet and WiFi (XFinity).
I've used Pale moon, Firefox (no extensions), Links 2 (text only browser), Slimjet (no extensions), and Safari (my wife's).
On an iPad with WiFi, the index page was up to date.
I've posted on the forums, but so far no conclusions.
It's not a big deal, but I would really like to understand why.
Thanks in advance.
