First, the "fixed" files are the same as mine, except they don't have a bit of code that is there to prevent non-ascii names from looking strange.
That specific error should be fixed in the latest version anyway.
If it is not please let me know.
If there is a bad profile link, it has to do with a steam ID not calculating properly.
A link to the stats page with the broken calculation would be helpful.

Does your webserver have MySQL?
I might add an option in the config to hide/show the add friend/send message buttons.
The map points I have not looked at yet, that page needs to be worked on.
I removed the copy of the plugin with the headshot fix because I thought it might have been causing eraserhead's problems, but it apparently was unrelated.
I post it again when I find it.
I'm not sure how I would do a graph, but it's something I would like to add.
