Sorry haha. And Not sure how it happened but I disabled the advanced footer and Chrome had a gap of like 2cm in the footer. I enabled the advanced footer again then redisabled and it's been fine since not sure how it happened. Only mentioned incase others had this issue.The social buttons will be the end of me. It was a fix for another bug that I overlooked in the overlay .
By the footer being not always sticky what exactly are you referring too?
