Using the current release of WFU I'm getting an error reported on syncing some files.
If I upload through WFU it will rename it to lowercase, generate the pre-defined smaller versions and all is well.
If I FTP the file up then go to synchronise, the file (still with some uppercase) fails when I try to synchronise it.
I get the error message with file: 20100527_Thierry_Bearzatto14.jpg
Warning: Wrong parameter count for set_time_limit() in /......./wp-content/plugins/wordpress-flash-uploader/inc/wfu-sync.php on line 76 Crunching (1/1): 20100527_thierry_bearzatto14.jpg Files imported to media library.
It looks like it does actually work, but it's an odd error to report when normally it works flawlessly.
