I wrote a code using the example of the google maps with php and mysqli, the code is working in other browsers but in the chrome whe I load this program the map displays and turns into blue or grey without markers. I am getting the grey screen or some times blue screen when I load this page in chrome browser.but the results will show inside div. After clearing the location settings,the markers appears. I have posted my code Please check it if I have missed anything.
