Re: Second Page Gone!
Error log access is highly dependent on your hosting setup. If this is a shared server, you might have a control panel and in there might be access to logs. What is your hosting setup?
If you don’t have or can’t find logs, then you can setup error logging for bbPress, then just log to a file for a while and try accessing this page 2 and see what gets logged. Then, find and fix the problem. I can post the code for custom error logging, or you can google for it.
