Re: WSOD on large number of elements in a form

http://httpd.apache.org/docs/2.0/mod/core.html#limitrequestbody
upload_max_filesize and post_max_size in your php.ini file.
Each name/value is limited to 1024 characters, if the form type is not
multipart.
Also look at memory size available for script ... the default 16M is not
enough, as cake itself uses about 6-9 of them for a not very complex
app. Notice that on certain distros the ini files for cli and apache
module are different, and that you need to restart apache after every
change. I suppose you use apache.
Also notice that certain browsers (cough, ie, cough) , in my experience,
have a hard time and break your post data if using many inputs and not
setting a multipart form.

Considering WSOD, is probably to have with your server (apache)
settings. Can you try to post the form to a simple php that's <?
print_r($_POST) ?>ing the form data ?, with reporting E_ALL ?

#tail -f the error.log file of the server to see realtime what's the
server saying about your attempt.
