+TROUBLESHOOTING
+--------------------------------------------------------------------------------
+
+  - "CORS error" in browser console:
+      CouchDB needs CORS enabled. Go to https://couchdb.kolpacksoftware.com/_utils
+      (Fauxton UI), open Config, and under "cors" set:
+        enable_cors  = true
+        origins      = *
+        credentials  = true
+        methods      = GET, PUT, POST, HEAD, DELETE
+        headers      = accept, authorization, content-type, origin, referer
+
+  - "401 Unauthorized":
+      Verify admin username/password in LiveSync settings.
+
+  - Sync not starting:
+      Toggle the plugin off and back on, or restart Obsidian.
+      Check the LiveSync log panel (Settings → Self-hosted LiveSync → Log).
+
+  - KasmVNC clipboard issues:
+      Use the clipboard icon in the KasmVNC toolbar to paste text into
+      the Obsidian window.
