I2c Problem Random Characters on LCD not values

i getting random characters not values on lcd display. ideas? please see below , attach photos of lcd , setup flowmeter

#include <wire.h>
#include <lcd.h>
#include <liquidcrystal_i2c.h>

#define i2c_addr    0x27 // <<----- add address here.  find i2c scanner
#define backlight_pin     3
#define en_pin  2
#define rw_pin  1
#define rs_pin  0
#define d4_pin  4
#define d5_pin  5
#define d6_pin  6
#define d7_pin  7

liquidcrystal_i2c  lcd(i2c_addr, en_pin, rw_pin, rs_pin, d4_pin, d5_pin, d6_pin, d7_pin);

volatile int flow_frequency; // measures flow sensor pulses
unsigned int gallons_min; // calculated gallons/min
unsigned char flowsensor = 2; // sensor input
unsigned long currenttime;
unsigned long clooptime;
void flow () // interrupt function
{
flow_frequency++;
}
void setup()
{
lcd.begin (20, 4); //change if need to
lcd.setbacklightpin(backlight_pin, positive);
lcd.setbacklight(high);
lcd.home();
pinmode(flowsensor, input);
digitalwrite(flowsensor, high); // optional internal pull-up
serial.begin(9600);
attachinterrupt(0, flow, rising); // setup interrupt
sei(); // enable interrupts
currenttime = millis();
clooptime = currenttime;
}
void loop ()
{
currenttime = millis();
// every second, calculate , print gallons/hour
if (currenttime >= (clooptime + 1000))
{
  clooptime = currenttime; // updates clooptime
  // pulse frequency (hz) = 60q, q flow rate in gallons/min
  gallons_min = (flow_frequency * 100 / 60); // (pulse frequency x 1 min) / 60q = flowrate in gallons/min
  flow_frequency = 0; // reset counter

serial.print(gallons_min); // print gallons/min
serial.println("gallons/min"); delay(100);

lcd.print("text");
lcd.print("text");
lcd.clear();
lcd.setcursor(0, 0);

}
}

you got i2c backpacked lcd display.
so need i2c library, ok.

but why include "normal" lcd library ?
delete

code: [select]

#include <lcd.h>
and see happens then.

if doesn't work have search more issues.
