Thanks for your assistance.
I have found the file “http://info.ohair.com/index.html” to be iffy. If I punch it in directly on my iPad4 (iOS 8.3) it works but when I went to it from an absolutely identical link within another Hype object on another page it tries to load but I get the “problem” message.
Go to http://info.ohair.com/questions1.html" and click on the Home item in the menu. This is the identical URL to what I punch in directly, so I’m not sure what is going on.
Just now when I got the message I found that I could select the URL field but instead of a the onscreen keyboard I’m stuck with the default bookmarks interface. I’ll restart the iPad and see if that sorts it out.
I have found that when I add the “questions1” Hype object to the inline layout I always get the “problem” error. It works well on its own. (Well, it did after the first attempt. The first time I tried it the Google Fonts were ignored. reloaded it and the fonts showed up.
