1: Request Error (ns_encodingforcharset):
Posted by Nima Mazloumi on 12/22/03 03:33 PM
Hi all,

I have a problem with SuSE 9.0. I upgraded from 8.3 to 9.0 which also upgraded the Aolserver from 3.3 to 3.4.2.

The server restarts properly without any error but when I try to access the page I receive the following message: 

Request Error

The server has encountered an internal server error. The error has been logged and will be investigated by our system programmers.

AOLserver/3.4.2 on http://dotlrn.uni-mannheim.de:8000

In error.log this message is shown:

Any idea what that could mean?

Greetings,

The reason we use 3.3 is because it has extra 'stuff' in it to handle non-English character sets properly.  It looks to me like the command ns_encodingforcharset is part of that, and there will be other things missing or not working right as well.  You'll need to go back to 3.3 to make things work again.  Or you could upgrade to 4.0, but I think there are still some questions about whether everything we need is working 100% in that version.

Yeah, Nima, what Janine said is right, you broke your AOLserver. AOLserver 3.4.2 is not supported by OpenACS, you need a version that is, which means either 3.3+ad13 or 4.0. There are some particular features (e.g., SSL) that might not quite be 100% in 4.0, but lot's of OpenACS maintainers say they've been using AOLserver 4.0 for a long time now so it should basically work. See the AOLServer 4.0 Support in 5.0? thread for more info.
