General Support: Cruft-free URL's break my site design

I've had my Plogger album running for a few months now and I've just decided to switch on the Cruft-free URLs function. The plogger gallery itself seems to work but my site design is now broken. I think all the links to my normal web pages, css file and images within the template have been disrupted. The only page which displays OK is the main gallery index page.

What do I need to do to fix this? My Plogger installation says I'm using 'Version 3.2.LastChangedRevision Beta' but I thought I originally loaded something with numbers like 549 or something. I'm using a modified default theme.

Annie,

We need to see a link to see what is messed up and why. If you don't want it public, you can "whisper" to any of the moderators (sidtheduck, kimparsell, ryanduff, mike) or email it to sidtheduck AT gmail DOT com.

Thank you. That worked.

May I trouble you to ask a few more questions please?

1) Is there a way of saving the output files as static html pages or do I need to take a snapshot of the site?

2) Is there a quick way of implementing a 301 redirect facility for all of my gallery pages now that I have changed all the URLs to the cruft-free version or will I have to implement this page by page?

3) Lastly, I tried to use the solution below to alter the underscore to a hyphen in the URL path but I still have underscores. My filenames are just numbers (to help me order my photos) but the albums have descriptive names which I'd like to be search engine friendly.

In file plog-functions.php find this lines:

// sanitize filename by replacing international characters with underscores
function sanitize_filename($str)
{
// allow only alfanumeric characters, hyphen, [, ], dot and apostrophe in file names
// the rest will be replaced
return preg_replace("/[^\w|\.|'|\-|\[|\]]/","_",$str);
}

and replace this "_" with "-" .

I did this and changed it to

// sanitize filename by replacing international characters with underscores
function sanitize_filename($str)
{
// allow only alfanumeric characters, hyphen, [, ], dot and apostrophe in file names
// the rest will be replaced
return preg_replace("/[^\w|\.|'|\-|\[|\]]/","-",$str);
}

ie. I changed the underscore in the return preg_replace("/[^\w|\.|'|\-|\[|\]]/","_",$str); to a hyphen.

Did I do it right or is this just a solution for photo filenames and not for the album part of the URL?
