Plugin doesn't work

Most of the times the issue can be easily fixed by reading this page.

Read the install tutorial again

Try again to follow the installation tutorial on a clean server.

Try to remove the new plugin, restore from a server backup, or downgrade the updated plugin/server version and check if the issue persists.

Update all dependencies, sometimes outdated JARs can cause issues.

Someone might have the same issue. Try also to use the search button.

Use the search button before submitting a report, people might already have reported it.

When you report something be sure to:

follow every single step of my tutorials and make sure to read all the wiki.
test the plugin on a CLEAN server (with only ItemsAdder installed) since it could be a plugin interfering.
use the latest version of the plugin, its dependencies and server.

If the problem persists, and you think it's a bug, send me these information when you report the problem:

Exactly what you did to trigger the problem
Server version, use /version command and send me the exact text it shows (use it in console to copy and paste)
Plugin version
Tell me if you edited the .yml files of ItemsAdder
Tell me if you edited the resourcepack
Zip ItemsAdder .yml files and send me them
Specify if the plugin shows error in console or in chat
Complete log of your server (not just a small portion of the error you see of ItemsAdder or I can't identify the issue)
