This isn't a site bug, but an error in a tutorial
Sorry if this is the wrong place to post it
All the entries regarding texlights tell you to add this line
@PointClass color(255 128 0) = info_texlights : "Texture Light Config"
But it's missing the final "[]" and won't work without them. Might be confusing for some people!
(full line should be:)
@PointClass color(255 128 0) = info_texlights : "Texture Light Config" []
