I get this when I launch the game

Im using these mods:

All Quest Objectives On Map
Indestructible Items
Fast Travel from Anywhere
Remove Weapon and Armor Level Restrictions

The game works without the mods but I want to know how to fix the script error to use the mods

Other than removing all mods, you have three options:
1. Use script merger and hope it successfully merges all of your mod scripts.
2. Contact the various mod authors for help with possible compatibility issues.
3. Remove all mods and add one at a time to see if you can get any to work together.
