I have recently noticed strange things happening to my permalinks. When I type in any permalink for my site, at start it seems to be working normally, but then I noticed the link itself changing and this line is added to the end of the link #.UPHxsPMzFMs . This happens for all the pages on my website except for the home page. Also recently I am getting lots of 404 errors and I am not sure if this has anything to do with it.
Does anyone know what’s causing this? And how to fix it?
