Whenever I try to right click a sign with command executing data the sign does not execute the command. It does not produce an error but I have deduced that the cause is this plugin as all the plugins I've used before and have not encountered this issue, Please find and fix whatever is causing this...

What?

EssentialsX does not have command signs.

Are you sure essentials is causing it and not oh the fact that 1.13 broke the heck out of selectors in every which way?

@BluePlastics EssentialsX does not have "command signs" as described by the OP, so that still doesn't make sense.

@WolfGameStudios Please clarify your issue. This does not seem to relate to EssentialsX whatsoever.

@md678685 my guess was he's attributing selectors not working to essentialsx since his signs have essentialsx commands attached to them. But we won't know for certain unless he replies.

Closing due to lack of response from @WolfGameStudios. If this is still an issue, please open a new report.
