I cleaned the cache and ported the "blog" node under main site node because I don't want to assign an hostname to blog node.

Do you have any steps to replicate the issue? Have you tried using the latest 3.x version?

The issue happened after republish the entire blog. The blog has a lot of article. The blog node was at the same level with the "home" content node. Any main nodes has "hostname". So I solved:

• delete umbraco xml file anche cache files
• I assigned an hostname to main content node
• I assigned an hostname to blog node, but for customer rule, I moved it under "home" node.

MAIN ISSUE: I lost tags and categories but the articles have them into backoffice.

Update: this happened after the customer move blog node.
