 * Hi, [@tareq1988](https://wordpress.org/support/users/tareq1988/)
 * I’m using WordPress 3.4 and the multisite setting with BuddyPress installed, 
   after upgrading to version 1.0 I get this error:
 * **Warning:** call_user_func_array () expects parameter 1 to be a valid callback,
   function ‘upload_size_limit_filter’ not found or invalid function name in /home/
   xyz/public_html/xyz.com/wp-includes/plugin.php on line 170
 * If this is a bug, hopefully soon be fixed.
 * Thank you for your really great plugin.

 * I think it’s happening for only Multi site users. Thats why I didn’t encountered
   this problem.

 * Hi Tareq,
 * first of all “GREAT JOB” – There’s a huge difference between V0.7 and V1.0 and
   I really like the new way of attachment upload,…
 * I already updated at an single WordPress site and there it’s working great. At
   another WordPress Multisite I get the following error and the “Upload image” 
   of the featured image upload isn’t working:
 * Warning: call_user_func_array() [function.call-user-func-array]: First argument
   is expected to be a valid callback, ‘upload_size_limit_filter’ was given in /
   www/xxx/wp-includes/plugin.php on line 170
 * It would be great to find a solution for that. Maybe someone has a fix or an 
   idear.
 * Thank you!

 * OK. As in Multisite the super admin is able to set the max_file_upload for all
   blogs I had to comment out a line (no. 145) in wpuf.php:
 *  // ‘max_file_size’ => wp_max_upload_size() . ‘b’,
 * Hope this helps some others, too.
 * Best!

 * Try the version from [github](https://github.com/tareq1988/WP-User-Frontend/zipball/master)
   and let me know if it’s working fine.

 * Hi, Tareq Hasan, glad to see my post quickly get reply.
 * I just use the version from github updates, error has disappeared and generally
   the plugin is working properly. But there may be the little bugs: the content
   field appear only when the “Content editor type” is set to “Rich Text (tiny or
   full)”, but when set to “Plain Text” the content field does not appear. In addition,
   the “Default post category” drop down selection is empty. Although this little
   bug not too annoying to me, for others might be a problem. Hopefully this can
   be fixed immediately.

 * I don’t see any problem with editor, working fine here.
 * Maybe those category has no post, thats why it isn’t populating. Will be fixed.

 * Oh yes, apparently that’s the problem. After I make a post, the category was 
   then show up. I’m sorry to be inaccurate.
 * Thanks, Tareq.
