Hi Robert,

When I upload files to the wiki, I do so by clicking the picture icon
when editing a wiki page.  I am "unaware" of URLs like the above, and
you shouldn't need to be aware of that URL either.

OK, I've just checked - yes, the pop-up window with title "Media Files
[Openwall Community Wiki]" has the exact URL you mentioned.

I think I haven't seen it display upload progress percentage at all.
Maybe this is somehow browser-specific.

It may be less.  We have these PHP settings:

post_max_size = 50M
upload_max_filesize = 50M

and DokuWiki derives its reported file size limit from them as follows:

/**
 * Returns the size uploaded files may have
 *
 * This uses a conservative approach using the lowest number found
 * in any of the limiting ini settings
 *
 * @returns int size in bytes
 */
function media_getuploadsize(){
    $okay = 0;

    $post = (int) php_to_byte(@ini_get('post_max_size'));
    $suho = (int) php_to_byte(@ini_get('suhosin.post.max_value_length'));
    $upld = (int) php_to_byte(@ini_get('upload_max_filesize'));

    if($post && ($post < $okay || $okay == 0)) $okay = $post;
    if($suho && ($suho < $okay || $okay == 0)) $okay = $suho;
    if($upld && ($upld < $okay || $okay == 0)) $okay = $upld;

    return $okay;
}

I'm not familiar with PHP internals to tell if any encoding overhead is
counted against any of these limits.

Try uploading a smaller file.  In fact, I'd prefer that you don't make
these builds that large.  Can you exclude the non-essential *.chr files,
like I do for official 1.8 tarballs?  Just refer to a separate archive
for those extras.

Just how slow is it?  Maybe you're hitting a timeout.

Thanks,
