 * I have pro version and all working fine until I try to upload multiple larger
   files – say 24 files of around 2.5mb each
    After the first few files have uploaded
   the progress bar stops working and only the first few files are listed in the
   drop down list. When I check on the server I can see that the files are still
   uploading and most of the time it completes (though not always) However the user
   isn’t provided with any feedback. On Firefox it eventually crashes the browser
   and Interet explorer just becomes non-responsive Here is my shortcode
 * `[wordpress_file_upload uploadpath="../subs_photos/%username%/%userdata1%" uploadrole
   ="administrator,subscriber,editor" uploaduser="all" uploadpatterns="*.jpeg,*.
   jpg" createpath="true" forcefilename="true" dublicatespolicy="maintain both" 
   adminmessages="true" debugmode="true" placements="title/userdata/filename/selectbutton/
   uploadbutton/progressbar/message" widths="filename:200px, progressbar:200px,userdata:
   200px" heights="filename:200px" userdata="true" userdatalabel="Job Ref:|t:text
   |s:top|r:1|a:0|p:right|d:"]`
 * I thought maybe if I added the gallery underneath, the page reload might sort
   out the problem. But gallery isn’t showing at all?
    Shortcode I tried for this
   is: `[wordpress_file_upload uploadpath="../subs_photos/%username%/%userdata1%"
   uploadrole="administrator,subscriber,editor" uploaduser="all" uploadpatterns="*.
   jpeg,*.jpg" createpath="true" forcefilename="true" dublicatespolicy="maintain
   both" gallery="true" postlink="true" forceclassic="true" adminmessages="true"
   debugmode="true" placements="title/userdata/filename/selectbutton/uploadbutton/
   progressbar/message" widths="filename:200px, progressbar:200px,userdata:200px"
   heights="filename:200px" userdata="true" userdatalabel="Job Ref:|t:text|s:top
   |r:1|a:0|p:right|d:"]`
 * Server settings are:
    max_execution_time 60 max_input_time 60 post_max_size 50M
   memory_limit 128M upload_max_filesize 50M
 * I’ve also added the following to the theme’s function.php file
 * @ini_set( ‘max_execution_time’, ‘300’ );
    @ini_set( ‘max_input_time’, ‘300’ );
 * Upload Big Files in Chunks is On

 * Well the plugin has not been tested for concurrent upload of too many files, 
   it may run into performance problems…
 * The plugin has a setting to define the number of files that will be uploaded 
   at the same time. The default value is -1, which means that all files are sent
   to the server at the same time. If the files ar too many, then this may cause
   bottleneck and eventually reject files.
 * This setting is inside wfu_constants.php file inside /lib directory of the plugin’s
   folder. On line 276 change WFU_CONCURRENT_FILES constant from -1 to 1. This way,
   the plugin will upload the files 1 by 1 sequencially.
 * This may solve your problem.
