Re: Empty delimiter?
Warnings in PHP are just that: warnings. They don’t prevent things from working. You should not show warnings on a production site.
So, the problems you are having are likely NOT due to those warnings. What are the problems you have with the forum, aside from and ignoring those warnings? Maybe you have a bozo problem (where your posts don’t show up.)
What can’t you do on your forum? What version of bbPress are you using?
