WP updates are causing me some font problems with older posts. Recently, I received malware intrusion warnings from my hosting service. I added a couple of new plugins which seem to have eliminated the malware, but one of them introduced a nee major glitch. While typing in a new post, suddenly the toolbar to the left moves right and deletes my work. I am advised to update PHP for security reasons. However… some years back, my consultant modified my Thee for me substituting Tags for Categpries. Updating PHP would undo that modification. I’m only modestly technical and I need some professional assistance.
