I recently switched from Essentials To EssentialsX, when i had Essentials i could use PEX just fine now that i have EssentialsX i can't use it when ever i make a prefix it doesn't apply to my name please help.

Essentials and EssentialsX use virtually the same exact config.yml file.

If you had prefixes programmed correctly in Essentials, that same config.yml file would work for EssentialsX. (They also both use "Essentials" as the name of the plugin folder.)

And since you claim to have had prefixes programmed correctly in Essentials, you already know how to program prefixes correctly for EssentialsX.

You're welcome.
