I've changed the header by elements customized.
I followed the video to close the header and add code to ADS.
Then the problem is happened, which is:
when i click pages from everything, the loading should be like a circle, but the loading icon is changed, its like an animation, I CANNOT EXPLAIN IT, BECAUSE ITS HARD TO SAY IT WITH WORDS.
I attached the video, please check it and get me back!!!!!!
