Thanks again, I fixed the language string problem by adding those lines as you suggested.
I am pretty sure the broken icons on the frontpage are caused by a bug. There are in fact two symtpoms:
- It messes with the default encoding of the frontpage. Even though my default encoding is UTF8, it causes the default to be ISO-8859-1 (my browser default?). This causes all the screen text to appear broken until I login, after which it looks OK. This happens in both IE and Firefox. After I delete the block from the site frontpage this problem goes away.
- The icons are doubled up and broken as shown in the screenshot above. However, this only occurs in IE; in Firefox all the links and icons seem to be displayed correctly.
Maybe the developers will have a look at this for me when they have time.
It's not really a serious problem because I don't really need to use this block on the site frontpage.
Thanks to the developers for this block and to Leo for helping out with the trouble-shooting.
