Error uploading file 500 - Strange error

Hi,

I am getting this error when I am trying to upload an audio file under the music tab.I have made my web host edit the php.ini file to increse the upload file size limit and all.

Strange thing is the support person from the web host is able to successfully upload the file and I can see it on the site. When I am trying to upload its giving me this Alert msg in black box"Error uploading file 500". Thisa aler is coming after the uploading is 100% done. Any help would be greatly appreciated.

Thanks

I recently had my my server changed from one to another... could this be an issue. Web host had checked all the PHP settings and they look fine.

Thanks
