Possible you have a “cookie salad” in your browser…

First, try to rename the old forum folder (before deleting it…)

Deactivate and reactivate the forum in the bp settings.

Be sure you installed the “new” forum without de old bb_config in the new location. Let the system work to make a new one.

You will see than in the bb_config that the tables of your new forum are called wp_bb_xxx

These tables are probably empty at the end of such a acrobatic update.

If it is the case, you have to copy the old bb_tables content into the new wp_bb_tables. Normally your old forum content is now showing in the new install.

And sorry for my english.
