I'm actually running it as is in 5.1.1a8 and it is working. So can't see why it wouldn't work in 5.1.0.
Ensure it is installed, sometimes the auto-install process fails and such.

Thanks...was an upgrade where it was already installed, so my money is on a template customisation breaking it. I'll investigate further.

Many thanks for clarifying it does work, I can now track down where I broke it. :)

In that case, the best thing to do is to test against the default style. If it's working there you'll know that the problem is in the custom style.

Yep...definitely something I've broken. I'm good at that sort of thing.

Many thanks.

Nice mod.. seems to not work if you have Style & Language Settings > cache templates as files enabled. Disabled works fine

Hmmm, this mod might add the pagenation on the fly, which of course would not work if the templates are cached as files. DBTech's vBOptimize (vB4 & vB3) has the same issues, they have a setting to Cache Templates in File System, but it breaks any mod that that modify templates on-the-fly.

It's not impossible to edit file template on-the-fly. Database and files, both ways the template content is saved in a variable that can be manipulated.
The problem is that in the file cache case it's not going thru the api so it can't be extended.

Is their any possible future for adding the pagination next to the topic in the main forum, not just when you go into the topic?

Well it's not really related to the point of this mod, but I may build it for you as a custom work. Contact me if you're interested.

Is it possible to add this pagination on a search results page as well?
