Make sure you haven't restricted the functions you want to use for the admins, here's what they are:
// ADDING FLAGS MEANS YOUR ARE STOPPING ADMINS FROM USING
// THOSE OPTIONS UNLESS YOU HAVE mani_reverse_admin_flags set to 1
// in your autoexec.cfg
//
// Restriction options are :-
//
// k = restrict admin from kicking players
// r = restrict admin from executing rcon commands via ma_rcon
// q = restrict admin from executing rcon commands from the menu
// e = restrict admin from the adminexplode command
// m = restrict admin from slaying players
// b = restrict admin from banning players
// s = restrict admin from running ma_say
// o = restrict admin from running ma_chat
// a = restrict admin from running ma_psay
// c = restrict admin from changing maps
// p = restrict admin from playing sounds
// w = restrict admin from restricting weapons
// z = restrict admin from plug-in config menu
// x = restrict admin from running admincexec commands
// y = restrict admin from running admincexec from the menu
// i = restrict admin from running blind commands
// l = restrict admin from running slap commands
// f = restrict admin from running freeze commands
// t = restrict admin from running teleport commands
// d = restrict admin from running drug commands
// g = restrict admin from running ma_teamswap and ma_balance commands
// j = restrict admin from running gimp commands
// R = restrict admin from running rcon vote

// V = restrict admin from running vote map
// Q = restrict admin from running question vote

// E = restrict admin from using ma_rates
// F = restrict admin from running burn commands
// G = restrict admin from running noclip command
// H = restrict admin from running ma_war command
// I = restrict admin from running ma_mute command
// J = restrict admin from resetting all the player ranks

// M = restrict admin from having custom skins to choose
// N = restrict admin from being able to set a players skin
// O = restrict admin from running ma_dropc4 command

// Y = restrict admin from running ma_beacon command
// S = restrict admin from running ma_setcolour or ma_setcolor
// Z = restrict admin from running ma_give and ma_giveammo

//
// An example would be if you wanted to prevent admin
// with steam id STEAM_0:0:2388333
// from being able to play sounds and rcon command
//
// STEAM_0:0:2388333 rp // Admin can't rcon and play sound !!
//
// Another example
// STEAM_0:0:3389333 kmc // Admin can't kick, slay or change maps[/align]
