Yes, that's the file.
Sorry I forgot to mention it in the first place.
Well, in our case, the application came up with an PHP error message within the custom fields - so apparently custom_fields.html was the culprit. Allegedly,
<?xml was parsed as php - so we just hacked it in peaces.
Is there any error mentioned in your case? Try the following:
1. Download the latest version of the Opera Browser. It has a very powerful tool built in to examine a page.
2. Load your page
3. Right click on the yellow loading bar and choose "inspect Element" (The Opera tool will open)
4. On the left side of the tool, you'll find the html, on the right, the css. Just select the html for the yellow bar - the applied css shows up in the right window. Now look for the declaration that makes the button being 100% height, floating and absolute (I cannot remember perfectly anymore). Uncheck the mentioned declarations, so that the layer is gone - or at least not above your navigation.
5. Close the inspection-tool (but NOT opera). The layer still should be gone now. So you can use the accordion menu - open each one to find the culprit. Once you found it, debug the code yourself or post the error message here.
