- Can't register (client close when they click the Register button)
- Don't have starter
- Can't battle (Because they don't have any pokemon)
- Can't use the chat
I think this problems are common,
but couldn't find any fixes to them.
If you still use nexus version, this mean you have setup troubles, probabily port related, cause I just test for you and it works fine.
What you can do if you are lazy is to try manually edit database of your users
I downloaded a Pokemonium version but It didn't have the movement fix so I thought it wasn't really worked.
Do you have a link to a good/stable pokemonium server?
