When using the Plupload with larger files (e.g. 45mb) it displays an error. PHP memory/max timeout/max upload all have more than enough to handle this.

what is the error??? 45MB image for processing will require much more than 45MB of php memroy - several hundred meg likely... but you might also have to increase the chunk file size of the uploader... but interested in error first...

odd. have never seen that error before... its an internal server error and not a file uploader detected one... memory errors, chunking, etc type errors are caught by the file uploader... not even sure what to make of that cryptic/unhelpful message...

Is this IIS?

guess we could try chunking the file but havent ever had to do that... its not an internal file uploader limit per se, just tested an allmost 100MB file...

the file uploader uses plupload - a 3rd party app same as WP uses for its media uploader...  can you upload the same file when creating a new wp post? 

will search the plupload forums for similar...

want to try adding chunking?  one line edit to the plugin...

so in sp-resources/forum-plugins/plupload/libarary/sp-plupload-forms.php...  find routine sp_plupload_script()

around line 209, find:

                    runtimes : '$runtimes',
                    url : '$url',

and after those two, lets add:

                    chunk_size: '1mb',

and see if that does anything...
