Ok, I found this in case anyone else needs to know. The server path is stored in the database serendipity_config table:

INSERT INTO `serendipity_config` VALUES ('serendipityPath', '/home/*****/nolaspearfishing.com/html/cblog/', 0);

I was able to edit it in php my admin, and my site is now back up ...

I am doing the same thing as voelspriet.

I have followed these instructions, and I am getting error messages about folder permissions, but the paths reporting errors are absolute, local paths to directories on my old server.

Cannot write to directory /home/u3/nolaspearfishing/html/cblog/templates ...
