Hi,
first time & recommended, try to upgrade to XOOPS 2.3.3 (the lastest one)
Turn on debug & get errors.
Nothing solve with it?
Uninstall & reinstall it (or push upgrade).
None yet? Try upload again newbb. Sometimes gave us a blank page because some ftp clients didn´t upload properly.
I think these are the best ways to do. I hope you will fix it.
Regards
