[Plugin: Universal Post Manager] Fatal error on update to 1.1.1

ok:
1.) i deactivated the plugin wp-downloadmanager,
2.) then activated universal-post-manager,
3.) then activated the plugin wp-downloadmanager
it seems working (no fatale error)
But in my site, the right sidebar lays over the posts and pages !! (nearly right the left sidebar)

i deactivated the plugin wp-downloadmanager, always the right sidebar lays over the posts and pages !!

i deactivated the plugin universal-post-manager, all works (but UPM ?? )

Hi RunningSocks!
This is php function name conflict, seems wp-downloadmanager plugin has a function with the same name “file_extension” as UPM.
You can fix this issue via this few steps:
1)Find and open in notepad
/wp-content/plugins/universal-post-manager/functions.php file
2)Find this script (line 588):

function file_extension($filename)
{
	return substr(strrchr($filename, '.'), 1);
}

3)Replace to this:

if( !function_exists('file_extension') ){
	function file_extension($filename)
	{
		return substr(strrchr($filename, '.'), 1);
	}
}
