What you could do to avoid the motd is disabled message is go in addons/ulx/lua/ulx/modules/sh/menus.lua and then just disable the whole ulx command by(at the top of the file before any code) typing --[[ then at the end of the file after all of the code type ]] . That should at least remove the motd is disabled message after a server restart, but the motd addon you got should still open either way, if it doesn't, it is probably a problem with the addon itself or that isn't the command. if there is a console command to open the motd then you can also make a custom ulx command to run the console command to open it. Also if you don't get any clientside errors then check the server console if you didn't already.
