Urgent help needed re page size!


New Email
Used my email as usual yesterday, everything fine.
Today logged on ok but the opening page that appeared is very strange. Like its been magnified x5 then squeezed onto the screen. I can barely read the words even with a magnifying glass.
What have I done?
My partner's opening page is also the same and in both cases the Mail.com log-in page is fine.
Any suggestions?
Obviously I can't see what I'm typing so I can't email Their own tech team.
