Re: Token invalid or missing on upload

You need to check in ?action=phpinfo these constants in the "Local 
value" column:

   post_max_size
   upload_max_filesize

The former needs to be larger than the latter, and in config.php 
$UploadMaxSize only matters if it is less than upload_max_filesize in 
php.ini.

The total post size is the uploaded file but also other data like the 
pmtoken, the current page name, the action=postupload, the new name of 
the file, possibly the author name.

The total post size needs to be less than post_max_size, otherwise it is 
fully rejected/deleted before even this comes to PmWiki. PmWiki first 
checks for the token, and as it is has been deleted, it returns the 
error.

There is also a Warning: "PHP Request Startup: POST Content-Length of 
XXX bytes exceeds the limit of YYY bytes in Unknown on line 0", but you 
may not notice it as the token error redirects back to the upload form.

I should think about how to catch these cases and show a more 
appropriate diagnostic but there are different upload forms, AJAX 
recipes, and other, this should be done carefully.
