Hi ,
Thanks for the quick response.
I have tried testing the site while disabling plugins one by one. what i found was, when i disable the google maps module the advance search takes only 3 seconds to display the results where as when it is enabled the advance search takes 17-18 seconds to display the results and most of the times it throws the error.
so i thought the maps module is the culprit here.
Can you please correct me if i am wrong ?
