If you encounter a workshop item version is different than server's error in Project Zomboid, you are not alone. This workshop error is common when Project Zomboid receives an update or mods become out of date. 

To fix the workshop item version is different than server's error, you need to update your mods or remove them. You can go about this by unsubscribing and resubscribing, and it will some times fix the problem.

It would also help if you create a collection with all of your mods to make the process faster. But In other cases, you will need to locate and delete the following folder called 108600. 

• \Steam\steamapps\workshop\content\108600 

After deleting the folder above, find and delete a file called appworkshop_108600.acf. You can find this file in the Steam workshop folder itself.

Restart steam once the acf file is deleted and let the mods redownload. If you have trouble redownloading the mods, make sure to verify the Project Zomboid's Steam files. Doing so will cause Steam to redownload the workshop mods.

That said, Following these steps will allow players to join servers after updating the mods, but there are a few more steps if you are hosting the server.
