Since the customer is "always right" that may be preferable to not  
using the colons.

ok -- my bad.

I commented out all my plugins from config.php and it worked.   
There's a plug-in conflict with

if ($action == 'edit' || $action == 'comment') {
     $EnableWhyBlocked = 1;

Now, don't ask WHY that would have anything to do with it.  :P  It  
happens if I include the blocklist code.

I should have tried commenting out cookbook and other custom markup.

In any case it works now.  Thank you.  now I need to examine my own  
plug-in ;)

Blocklist calls $page_name = ResolvePageName($pagename); -- if that  

Another odd thing:  when the blocklist (3) is disabled, the "broken"  
link leads directly to an edit page.  When enabled, the link (http:// 
n=Simile.OfMiceAndMen:SteinbeckJohn:HerHairHung?action=edit) leads to  
a screen that says 'The page  
"Simile.OfMiceAndMenSteinbeckJohnHerHairHung" doesn't exist. (Create  

I didn't make it do that on purpose ;)  Why is the doesn't exist  
message coming up suddenly instead of the page edit form?

I ran over the Blocklist3 -- it's mainly a class-based recipe, so I  
made sure to rename all cookbook-only non-class variables to  
"$bl_..." to absolutely make sure it's not a variable conflict.   
Other than that I can't see what's wrong with it.   Except that it  
really shouldn't execute the bulk of it's code unless the form has  
been submitted ;) -- I don't even think the recipe checks the  
pagetitle for whether it contains blocked words.

I copied your code then started messing around with it, trying to  
convince it to work.  In any case, I found the conflict (weird!).

LOL -- like I said, I started messing around with it.

Actually [^...] means "don't match anything in this set" but yes, the  
hyphen would be a range and that's messy.

It wasn't the recipes -- I did process of elimination once the  
commenting out all custom garbage worked.
