| Problem | Likely Cause | Solution | |---------|--------------|----------| | “Invalid JSON” when uploading | Corrupted download or wrong file format | Open the file in Notepad++ or VS Code; validate with JSONLint. | | Preset loads but no effect | Mismatched effect name (e.g., old “Rainbow” vs new “Rainbow 1”) | Update WLED firmware to the version the preset was made for. | | Colors look weird (all red/blue) | Different color order (GRB vs RGB vs BRG) | Go to Config → LED Preferences → change “Color order” to match your LED strip. | | Preset is too fast/slow | Speed scaling changed between WLED versions | Manually adjust speed slider – it won’t break the preset. | | Only first 10 LEDs work | Preset was made for a different segment | Ensure segment 0’s “Stop LED” matches your total LED count. | intermit
