Why do I get this error message

[AimeeH]

I'm using safari on iPad mini. I keep several pool school articles open on different tabs and I get this message constantly

Can you first try to refresh the page and see if it still does it. If it does it again please let me know what article it does it in.

As I hit close on the error message, the page refreshes. It is just annoying not hampering. Confirmed the error on:

Table of contents
Slam article
ABC's article

Didn't seem to on the chlorine/Cya article

Thanks for your help

Mine does that after a few days of a page being open. Hit reload and it's good for another few days.
