Hi. I looked at the site and could not find the problem. Such blank page 
happens, as Peter K.H. Gragert said in a parallel message, when there is a 
call to an unrecognized function, preceded by "@" (which means "suppress any 
error messages by this function"). This may happen if a script expects a 
native php function to be available, and it isn't (php compiled without, or 
function disabled by safe mode), or a user written function that should be 
there but isn't (file not included?). I don't know for sure.

What I can suggest is to install a new, clean, independent pmwiki in another 
directory of this site, and see if editing works,
* without passwords and
* with passwords (set the standard page password by calling Page?action=attr).

Don't install AuthUser or UserAuth yet, nor any other recipes.

1. It may be a session problem (pmwiki tries to write session files in a 
write-protected or non existant directory) but in that case it should issue a 
warning message.

2. If it still doesn't work, if you cannot edit, the problem is with PmWiki 
and I hope that Patrick could look into this one.

3. If it works, if you can edit pages without passwords, and also with 
passwords, then the problem is in one of the recipes that you installed on 
the main site. You should:

   * Install the same skin, test if editing works (if yes, skin is OK).
   * Install one recipe, test if editing works (if yes, this recipe is OK).
   * Install another recipe, test, etc. 

When you find the recipe with which the editing doesn't work and you get a 
blank page, tell us, and/or try to contact the maintainer of the recipe.

Thanks,
Petko

P.S. I was able to see the site for a while, but now it enters an infinite 
redirect loop. I hope it's temporary.
