Suddenly everything is smaller! The script, the adverts, even the log-in box. I can hardly read the wording on the dashboard, so getting very difficult to find anything.

Only thing that has changed is that I did a theme re-load last night as recommended by some security software.

Any ideas please. Website may look normal to others but not to me - it was much clearer.

Advise please. Mnay thanks.

check your browser zoom level
what is the url?

Yes, that was the problem, just solved. I did not realise that zoom could affect just one website like that and not others. Easy when you know how! For those who don't know, control plus + will increase the size of everything and control plus - reduce it.

Thanks JD. Peter.
