Persistent page errors

We are experiencing some new and pretty persistent errors on our courses as of this week. No clue yet what causes it, but it certainly is annoying. What am I experiencing? I have recently finished a rather big course, where the AWT-file consist of little over 600 pages. Essentially it is made of 4 different chapters which represent the same 150 pages of course material, but in 4 different languages. So basically every image and/or textbox is present in the course for 4 times, one for each language. Where able, I use the same image for all 4 languages.somewhere along the line it all goes wrong. One page in one of the four languages is being load differently, and has errors. The errors can be defined by the nice IE yellow-triangle on the lower left bar of the IE browser, indicating that something is wrong (usually JS-errors go there). Hoewever, that same page on the other languages is doing just fine.What have I tried?I have tried to delete the image and replacing it with another image. No luck there. I have tried to delete the page and creating a new one, copy-pasting the contents. No luck there either. Everytime I get the same error on the same page.I am absolutely sure the right pages get loaded, as well as that the cache does not hold the error-pages in any way. Other PC's on other places have the exact same errors.Weird stuff?What is most curious is the fact that none of the errors appear in the preview mode. Everything is fine there, as well as physically on the FTP-server to which we upload the course material.What could this be? I'm clueless here..
