Layout / Ansicht verändert sich ständig

Hallo, bei meiner Website verändert sich das Layout bzw. die Ansicht. Die Schrift verändert sich, das Video (verlinkt mit Vimeo) auf der Startseite wird winzig. Wenn ich den Cache im Dashboard lösche, dann ist der Fehler behoben. Nach ein paar Stunden jedoch tritt er wieder auf. Weiss jemand Rat?
