PHP Warning: fread(): Length parameter

Hi, I am consistently getting a PHP warning containing the following:

PHP Warning: fread(): Length parameter must be greater than 0 in /public_html/halofinancial.com/wp-content/themes/enfold/framework/php/function-set-avia-backend.php on line 1025

This appears to be related to the following

if( ! function_exists( 'avia_backend_create_file' ) )
{
	/**
	 * Creates a file for the theme framework and optionally verifies content
	 * 
	 * @param string $file
	 * @param string $content
	 * @param boolean $verifycontent
	 * @return boolean
	 */
	function avia_backend_create_file( $file, $content = '', $verifycontent = true )
	{
	    $handle = @fopen( $file, 'w' );
	    if( $handle )
	    {
	        $created = fwrite( $handle, $content );
	        fclose( $handle );

	        if( $verifycontent === true )
	        {
	            $handle = fopen( $file, 'r' );
	            $filecontent = fread( $handle, filesize( $file ) );
	            $created = ( $filecontent == $content ) ? true : false;
	            fclose( $handle );
	        }
	    }
	    else
	    {
	        $created  = false;
	    }

	    if( $created !== false ) 
		{
			$created = true;
		}
		
	    return $created;
	}
}
