Hello

If user moves back in topic, example from page 2 to 1, page loads forever. This didnt help:

Test:

http://hoitajat.net/foorumi/topic/16717-terveystieteen-pääsykokeet-2015/?page=4

Try to move page 3

Try to remove your tracker code. It takes 38sec to load the files and one timed even out...

Disabled analytics, emptyed cache, didnt help.

Nope, didnt help

And it jams only when moving inside a topic.
