Error: Invalid Title?

After upgrading my wiki to from 1.1 to 1.2 this morning, I've found
that any attempt to view or edit a page that has an apostrophe in the
title will return an error page. I find this extremely annoying --
even crippling -- because a significant number of articles on my site
have (or will need) apostrophes in their titles.

Does this have anything to do with the fact that I switched the wiki
from ISO-Latin to UTF-8 when I upgraded? Please tell me there's some
way to get back the functionality!

Thanks,
Dan Carlson

If you can change the PHP configuration, try turning off the
"magic_quotes_gpc" option.Alternatively, try changing this bit of
index.php:

if( isset( $_SERVER['PATH_INFO'] ) ) {
$title = stripslashes( substr( $_SERVER['PATH_INFO'], 1 ) );
} else {
$title = stripslashes( $_REQUEST['title'] );
}

(the stripslashes calls aren't presently there).

Let me know if that clears it up, I'll get a 1.2.1 out soon...

Okay, that let me see the edit page, but when I tried to save it, it
gave me the same error page again...

I'm using the ’ mark-up for an apostrophe, and I'm having no
problems.

I've just located the problem, at least in the functional sense:

http://memoryalpha.st-minutiae.com/en/index.php/Memory_Alpha:
How_to_edit_an_article_so_long_that_you_can%27t_edit
http://memoryalpha.st-minutiae.com/en/index.php?title=Memory_Alpha:
How_to_edit_an_article_so_long_that_you_can%27t_edit

The first URL, where the PHP variable is compressed out, does not work,
while the traditional style with "title=" actually DOES work.
Something's wrong with the URL parser, it appears.

Hope this helps!

Could you try this quick test script?

<?php

$magic = get_magic_quotes_gpc() ? "on" : "off";
print "Magic quotes are $magic.";

$path = $_SERVER['PATH_INFO'];
print "Raw path is: $path\n";

$stripped = stripslashes($path);
print "Stripped path is: $stripped\n";

?>

Then go to /blah/scriptname.php/Apostrophe%27s_some_trouble

It should print out the following:

Magic quotes are on.

Raw path is: /Apostrophe\'s_trouble

Stripped path is: /Apostrophe's_trouble

Now, on my test box, with magic quotes on, the apostrophe title does
with with index.php/Apostrophe%27s after making the hack fix I
described earlier:

if( isset( $_SERVER['PATH_INFO'] ) ) {
$title = stripslashes( substr( $_SERVER['PATH_INFO'], 1 ) );
} else {
$title = stripslashes( $_REQUEST['title'] );
}

(adding the two stripslashes() calls) Make sure they're both in there.

*smacks head*

When I added that fix the first time, I only added the SECOND
"stripslashes" incidence, and not the first. Stupid, stupid, stupid!

Sorry to cause confusion.
