When I attempt to edit the recently updated Home page it does not show the normal screen but shows a whole string of letters and numbers. e.g.

src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAASgAAADGCAYAAABhPh1fAAAgAElEQVR4Aey9d3Rd1b01ev/4xnjvje+mgHGTJav3YlmWbLkXbGwMGNOMMb04lNAhCS0kF0gIJUASQgo1QOjVxr3Lsnrv1VZvp+9yqqT5xvyts2VBuHkJScbNG580xhr76Jx99l5777Xmmr/5m2ud//D7/ZgqU/dgqg1MtYH/6TaAr/n7j//pSk2df6pjTLWBqTbANsC/8fHxL8HUFEBNMcgpBj3VBv4t2sAUQE01xH+LhjjFmKYY09e1gSmAmgKoKYCaagP/tm1gCqCmGue/beP8uhF16r3/s5jWF etc.

If I revert to the previous Revision this isalso not editable.

Suggestions please.
