Fixing Reimagined GUI Not Showing Up or Not Applying
If the dark interface never appears after you enable the pack, the cause is almost always pack order, a conflicting pack, or a stale selection. Work through these checks in order.
Check Pack Order and Conflicts
1. Open Options → Resource Packs.
2. Look at the Selected column. Any pack listed *above* Reimagined GUI (Dark) that also edits GUI textures will override it.
3. Drag Reimagined GUI (Dark) to the top of the Selected list.
4. Click Done and reopen a menu to test.
If you run a full texture pack that already includes its own GUI, the two will fight. Disable the other pack temporarily to confirm which one is winning.
Force a Reload
Sometimes the game caches the old interface. Press F3 + T to reload all resource packs without leaving the world. If that fails, quit to the main menu and re-enter the world.
Verify the Files
Open the pack folder from the Resource Packs screen and confirm the pack's folder is present and not nested inside another folder. A pack placed one level too deep will be listed but apply nothing. Move it up so its contents sit directly in the pack root, then reload.
