I checked another site and it's got only one entry in this table as well. Slightly different, but about the same.
Yeah, there would be one entry (row) of data, the question was related to what fields are in that table.

Now that I've looked at the correct version of the code (I was looking at some 4.x version), might I suggest executing the following in tools->Install SQL Patches and then a little navigation?
Code:
ALTER TABLE ceon_uri_mapping_configs DROP language_code_add;
Then, navigate to the Ceon URI Mapping (SEO) Config (likely will fault again), add ?check-config=1 to the end of the browser path and move forward with that address. Looks like should get a success install/upgrade. If not, then perhaps there is more to the error log? Have the files been removed that are directed in the instructions? Code seems to direct insertion of the field that is considered missing and to do so in a step-by-step sequence.
