I had to manually import forums from bbPress to Discussions using a CSV sheet with the database in phpMyAdmin as there is no import option for Discussions.

It seems all was imported OK, except the date shown on the category view is strange. When you open a post, the correct date shows, and the correct date shows in the admin side too.

What can I do to correct this? I've cleared the site's cache, cleared my browser's cookies and cache, I've run the Discussions database scripts from admin, and I've checked, repaired, optimized the discussions table in phpMyAdmin but nothing seems to fix this.

Any suggestions would be a big help. Thanks!
