WP, iFrame & IE8

I have recently developed a blog that has then been embedded via iframe into a pre-existing website. For weeks, almost a month, the blog loaded fine, all images, formatting, CSS, etc. loading correctly and cross-checked in all browsers.

As of two days ago the blog is not properly formatted or and is missing parts when viewed in IE8.

The link is: https://www.jeanshin.com/blog.htm

On the right-hand sidebar you will see “Fabrication”, and “Installation”. These are only TWO of the six total pages that were previously visible.

Any help would be greatly appreciated, as we are under a tight deadline for the project.

Thank you.
