We have a Wordpress site that suddenly stopped displayed posts in tags, categories or menus. That is, if you click [login to view URL], it would return "no posts to display" even though the category is showing dozens of posts in the dashboard. The same happens for tags. The menu doesn't display anything.
Steps we have taken:
1) Disable all plugins and remove their tables from the database
2) Reinstall Wordpress and transfer the site
Please respond with specific ways you want to solve the problem and how long it would take you.
We will ignore generic bids.
