Uh oh, I broke the Wiki

[Layne Lund]

Well, one of the pages in it, at least. Let me explain before you start jumping on my back, though:
I am adding some information to the FAQ about how to set the class path in Linux. After submitting some of my changes to see how they show up, the Wiki throws an exception when I try to access the page. You can visit http://test.javaranch.com/wiki/view?HowToSetTheClasspath to see the error message for yourself, so I won't paste it here. Can I do something to fix this myself? Or does the admin need to do something? Please let me know and I'll be more than happy to help out.
Layne
p.s. I saved the original content along with my additions as a local text file. I can restore them as soon as I can have access to this particular WikiPage.

Thanks for letting us know, Layne. I worked with this a bit; the previous text is currently restored, but the page is (apparently) not editable at the moment. I'm not sure what's going on; will give Friki creator Frank Carver a chance to take a look before I attempt further meddling.

[Layne Lund]

Will you keep me posted on the progress of this page? I'd sure like to add my bit about Linux. Feel free to email me; my address is listed under my profile.

If Jim doesn't beat me to it, I'll sort things out tonight when traffic on the wiki should be lower than during the day.

[Jim Yingst]

The page is restored now, though the history is gone. Well, it's been moved to a backup directory, because I couldn't figure out how to make my hand edits mesh with the history without creating other problems. We're still working on the underlying problem that set this off initially. Hopefully Layne won't break it again right away.

[Layne Lund]

I sure hope I don't break it again any time soon, either.
Fortunately, I had my modifications on the clipboard so I could paste them to a text editor and save them as a local file. I finished my comments and posted them to the Wiki now, so you don't have to worry so much about the archived/backed-up version.
Thanks a lot for your help. I hope you figure out how to fix the underylying problem so it doesn't happen again.

I also broke the Friki Wiki
I wanted to save my data (new pages) on a share drive which is not a server so I entered its address. Start up shows.

But before the first page can be displayed a regular expression throws up.

description The server encountered an internal error () that prevented it from fulfilling this request.

The following looks a little funny because '\n' was used to break the line.

Poking around I am sure my address did it but I cannot figure out how to change the regular expression to allow the address or how to remove the address (short of reinstalling).

Regular Expression was in the original wiki.transform
# remote wiki link
FilterReplace wiki.RemoteWikiLink !(\p{Alpha}+)[^\s\n\Z}]+)!&~1{&1}{&2}!

Any help appreciated.

I also am looking for an explanation of the tilde (~) in above &~1 vs &1

Ann, did you break our installation? If so, did you fix it? Are you just asking a question about Friki?
