As you can probably tell from the title I'm not a web developer. I signed up with SquareSpace to avoid having to do things like this.
Ive taken a look at the more information page for the warning on Google but it might as well be written in Swahili.
Is this something I need to be worried about? Its appeared after posting several new blog posts so an educated guess says theres something wrong in the posts.
If anyone has a link to maybe a blog post that explains this and the solution very simply for people like me who only know basic formatting html that would be very helpful too.
