in the last couple of days some websites are taking their time to load/update on my screen. Like they're not caching. For instance - https://penarthnews.wordpress.com And even my own site's homepage - http://sjleworthy.com Just flicking up and down the page leaves blank white spaces for longer than i'd like, especially on my own page. Is there a caching button/option i'm missing? Does this happen with you? My internet is still lightning fast.
