How to Fix the Simplistic GUI Pack Not Showing Up or Looking Wrong

The Pack Does Not Appear in the List

If Simplistic GUI is missing from the Available packs column, the file is probably still zipped incorrectly or nested inside an extra folder. A resource pack must contain its assets folder and pack metadata at the top level of the archive, not inside a subfolder. Re-download or re-pack it so the structure is flat, then press the refresh button in the Resource Packs screen.

The Pack Is Enabled but Textures Look Unchanged

Check the Selected list order. Another pack above Simplistic GUI may be overriding the same textures. Drag Simplistic GUI to the top. Also confirm you are looking at the right profile, since each world or launcher profile can have its own active pack set.

Only Some Elements Changed

Partial changes usually mean a conflict rather than a broken pack. Identify which pack supplies the unchanged element by disabling others one at a time. Once found, reorder so Simplistic GUI takes priority, or accept the mix if you like it. If the whole interface reverts after a game update, simply re-enable the pack, since updates can reset the selected list.
