“Portfolio is not showing, 404 not found error instead”

This question applies to Astrum - Responsive Multi-Purpose WordPress Theme, Centum - Responsive WordPress Theme, Incredible - Responsive WordPress Theme and Nevia - Responsive WordPress Theme


You need to go to wp-admin -> Settings -> Permalinks and switch them to default, hit save, and than switch back to previous setting and save again. It will clear permalinks table with wrong records and fix this issue.
