Has any body had this sort of problem before. The text mainly in input field descriptions turns to weird icons see image. I have deactivated all plugins and changed themes several times but same happens. However it sometimes starts working and then will just suddenly to the same thing again. In the front end the font family is open sans which will work sometimes and then sometimes it will do the same thing you can see in the image weird icons. But when the icons appear if I turn of the set font family is will work and use the default browser font family.
