Validation when publishing Expert Adviser

I received a "Not enough money" error, how can I fix it?

No issues were encountered in backtesting or live trading.

bool CheckMoneyForTrade(string symb,double lots,ENUM_ORDER_TYPE type)
  {
//--- Getting the opening price
   MqlTick mqltick;
   SymbolInfoTick(symb,mqltick);
   double price=mqltick.ask;
   if(type==ORDER_TYPE_SELL)
      price=mqltick.bid;
//--- values of the required and free margin
   double margin,free_margin=AccountInfoDouble(ACCOUNT_MARGIN_FREE);
   //--- call of the checking function
   if(!OrderCalcMargin(type,symb,lots,price,margin))
     {
      //--- something went wrong, report and return false
      Print("Error in ",__FUNCTION__," code=",GetLastError());
      return(false);
     }
   //--- if there are insufficient funds to perform the operation
   if(margin>free_margin)
     {
      //--- report the error and return false
      Print("Not enough money for ",EnumToString(type)," ",lots," ",symb," Error code=",GetLastError());
      return(false);
     }
//--- checking successful
   return(true);
  }

As suggested by Yashar, you should always check using the method from the article as different brokers can have different limits and for some users the EA might run into issues/errors ("Not enough money" error for example) during live trading.
