That is probably because the string is to short, can you show us the OnPlayerText from the luxadmin script?

Or just increase the string, for example:

pawn Код:

//OnPlayerText
new string[50]; //this means only 50 letters can be used
//make it
new string[128]; //im not sure but SAMP has a chat limit anyway

You can also choose to remove it but you might risk getting some compiling errors if you do not know how to remove a string properly from a piece of code.
