Ah ha: Thank you for asking that question. I looked at the list (which is now up to 309 pages) and discovered the problem.
If you try these pages (at the moment... before I fix them!) you'll get no content:http://www.managedaccountreview.com/ja/currency-hedging.htmlhttp://www.managedaccountreview.com/de/managed-forex
This is what is going on: I use 301 redirects whenever I see a 404 error. BUT as I have just now realized, the source I was using to "collect" the 404s was not comprehensive. It missed a number of pages. So google webmaster found them (in a way) by telling me that I had all these pages without titles.
The real story is that the pages "without titles" are 404s or other errors. I simply need to create 301s for them.
