Models Not Moving

Ok on my dark rp when I make a charactor ( Not all of them ) I always end up at the end with it’s model like not moving I meen you can move but the model doesn’t move, it just has it’s arms in the air and it’s legs dont move.
But these models I use are the same as some other server’s use. Why does it do it with me and how do I solve it ? Thanks

Hang on on your dark RP server or on your dark RP plugin when you join other servers?

English please.
Do you meen is it on a server or single player ?

Did you seriously just complain my English? I mean if it happens if you join people or if it is on your server

Ok Ok, I dont have a server ok, on my SINGLE play dark rp gamemode ok. Am saying “But these models I use are the same as some other server’s use” meening for peoples servers they use the same models and it works but not on my single player gamemode
