This has happened to me a number of times, but today's instance is very strange
Viewing the Formula 1 topic, on page 415 out of 423.
When I press any of the next pages 416 etc, the ">" or "Last >>", it reloads page 415, showing page 415 selected. The link shown is "https://www.pprune.org/jet-blast/471034-formula-1-a-418.html" etc.
When this normally occurs to me there is only one next page - to have 8 next pages that don't show is very strange.
This occurs for me on Edge, Firefox & Chrome
