I was trying to restore my backup to a new server, and it showed some errors. The log is here: Ubuntu Pastebin The error maybe: PG::UniqueViolation: ERROR: could not create unique index "unique_index_categories_on_slug" DETAIL: Key (COALESCE(parent_category_id, '-1'::integer), slug)=(5, ) is du…

@Rasin , This should now be fixed as of: https://github.com/discourse/discourse/commit/7ba914f1e10d90b1e4d25b0ab2427c94df456eae Thank you for bringing this to our attention and I’m sorry for any inconvenience. Let us know if you have any other problems.
