DarkRP 2.5.1 Text Screen Limit

I need help. I installed Textscreens on my DarkRP server, and when ever I tried to use the Textscreen the limit says you’ve reached your limit. Help me fix this please, there’s no lua errors or errors in general.

sbox_maxtextscreens number in server.cfg

Didn’t work, it’s a addon called “TextScreens” not for WireMod.

If it’s this one, the command is what nickster50 said.

Doesn’t work. I put the code in server.cfg and autoexec.cfg but it didn’t work. I’ll just try to reinstall it.
