When I look at the topics page in the backend word press page, the only data column that shows up is “Freshness”. I tried to make some modifications to the code, and I must have messed it up. Does anybody know what file controls this page?

The lesson you’ve learned is more important than any answer you will get…

Don’t modify core files.

You’ll want to delete the bbPress directory completely, and replace it with a new installation.
