You haven't stated anything about the modpack or anything else that someone trying to troubleshoot would be able to help with. There aren't many people on here with the knowhow so you need to give as much info as possible, and be patient.
I can tell you straight away that EnderStorage has had an issue from the log:
Code:
net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from EnderStorage (enderstorage)
Caused by: java.lang.RuntimeException: EnderStorage was unable to read it's data, please delete the 'EnderStorage' folder Here: C:\Users\truls\Documents\FTBRevelation\minecraft\saves\Truls LP\EnderStorage and start the server again.
and again here:
Code:
| LCHIJAE | enderstorage | 2.4.6.137 | EnderStorage-1.12.2-2.4.6.137-universal.jar | f1850c39b2516232a2108a7bd84d1cb5df93b261 |
The E at the end of that string of letters at the start signifies an Error
