Hi, Onimaro.

I assign developer to this thread.
@developer: I left a notice in "Notes about the thread".

Hi, Onimaro

That error notice only warning, and will not any fatal error. Because your server error mode using EALL (error all). I already put new condition at that line 206

From
if (!$thumbFileName)

To
if (!isset($thumbFileName))

public function getPlayerHTML($width=null, $height=null, $defaultView=true)
	{
		$id		= ($this->type=='file') ? $this->id : $this->video_id;
		$width	= ($width) ? $width : $this->_width;
		$height	= ($height) ? $height : $this->_height;

		if ($defaultView)
		{
			$html		= $this->_provider->getViewHTML($id, $width , $height );
		} else {
			$html		= $this->_provider->getEmbedCode($id, $width , $height );
		}

		return $html;
	}

I don't know bat now I have

Now I will try to install the version 3.2.0.2 if things improve

I have remove all activity now the home community working good
I still have problems with cron

Ok conversion on mp4 don't woking in my site so I change vedeo.php as old jomsocial for working whit flv video and working all good.
For me is good idea if you could put this in the administration to change these two settings.
Conversion flv or mp4
