Does not work with unofficial channels.

[Cat5TV]

The mod allows login when using official channels (eg., #ThePixelShadow) but not when hosted in an unofficial channel (eg., ##ThePixelShadow-Lego).

"The server needs to be in its channel for anyone to log in."

The server is in the channel.

The short ver­sion is that of­fi­cial chan­nels (also known as pri­ma­ry chan­nels) are named start­ing with one #, un­of­fi­cial (top­i­cal or about chan­nels) start with ##. If your chan­nel is not an of­fi­cial one, please use ## at the start of the chan­nel name, or you may be asked to move.
