well, tapatalk is 3rd-party and we won't maintain it (especially because it's a paid service - so they should fix stuff, not us). Can anybody check if this also happens on other myBB boards with the tapatalk plugin installed?

It's also happened on the UK Vapers forum - which uses myBB. According to their Admin guy..

Yes, there is an update: I've fixed it
If you have been getting weird errors in the last hour or so, that would have been me trying to track down the cause of the problem, which I eventually did and fixed

There was a bug in the Tapatalk plugin which I've now fixed (don't know why the guys at Tapatalk couldn't do it ). If you want the technical details, read on, otherwise just enjoy

Basically, when you start a search in MyBB (this forum software), you pass the search function a search id (sid). This is then used when you get more results, next page, etc. The tapatalk plugin was generating the sid correctly, but wasn't storing it in the current session state (which is data that's carried across between pages for the user). So, when you went for more pages, it was using an unitialised variable and throwing that error because it couldn't find the search it had started.

What I did to fix it was to change the code and put the sid into session state every time it is generated, and to pull it from session state when fetching more results, and it's all working now.

Does this help?
