With your advice, I tried to test my web with most module unpublished to shorten loading time. If you check our web now, it only have head and tail.
test mark 3-4s for loading time. but still translated pages are not coming.
So, I wonder if it's really problem you advised or other problem. Could you please check what is exact problem?
gtranslate is very important function in my pages and I really need to make it normal urgently.
