Problem with EM admin page and scope function

Hi guys,

after updating to 5.5.3 I get a white page when I go to EM > Events in the backend. When I go to my EM > Recurring events page in the backend all my recurring events are listet.. Any ideas?

Next issue: To display certain events in a table view I use this code in my page:

<table>

<thead>
      <tr>
        <th>Day</th>
        <th>Time</th>
	<th>Level</th>
	<th>Studio</th>
	<th>Teacher</th>
	<th>Infos</th>
       </tr>
   	</thead>

 <tbody>
[events_list scope="this-week" limit="100"]
  <tr>
  	<td>#_ATT{Day}</td>
    <td>#_EVENTTIMES</td>
    <td> #_ATT{Level}</td>
    <td>#_ATT{Studio}</td>
    <td> #_ATT{Teacher}</td>
    <td>#_ATT{Infos}</td>
  </tr>
[/events_list]
</tbody>
</table>

I figured out that the problem is the scope=”this-week” which doesn’t work anymore since the update. The corresponding code in my functions.php is:

$today = getdate();

	add_filter( 'em_events_build_sql_conditions', 'my_em_scope_conditions',1,2);

if (date('w') == 0)
{
    function my_em_scope_conditions($conditions, $args){
    if( !empty($args['scope']) && $args['scope']=='this-week' ){
		$now = time();
        $start_date = date('Y-m-d',strtotime('monday last week', $now));
		$end_date = date('Y-m-d',strtotime('monday  last week + 6 days', $now));

        $conditions['scope'] = " (event_start_date BETWEEN CAST('$start_date' AS DATE) AND CAST('$end_date' AS DATE)) OR (event_end_date BETWEEN CAST('$end_date' AS DATE) AND CAST('$start_date' AS DATE))";
    }

	    if( !empty($args['scope']) && $args['scope']=='next-week' ){
		$now2 = time();
        $start_date = date('Y-m-d',strtotime('monday  this week', $now2));
		$end_date = date('Y-m-d',strtotime('monday  this week + 6 days', $now2));

        $conditions['scope'] = " (event_start_date BETWEEN CAST('$start_date' AS DATE) AND CAST('$end_date' AS DATE)) OR (event_end_date BETWEEN CAST('$end_date' AS DATE) AND CAST('$start_date' AS DATE))";
    }

    return $conditions;
}

}
else
{
    function my_em_scope_conditions($conditions, $args){
    if( !empty($args['scope']) && $args['scope']=='this-week' ){
		$now = time();
        $start_date = date('Y-m-d',strtotime('monday this week', $now));
		$end_date = date('Y-m-d',strtotime('monday  this week + 6 days', $now));

        $conditions['scope'] = " (event_start_date BETWEEN CAST('$start_date' AS DATE) AND CAST('$end_date' AS DATE)) OR (event_end_date BETWEEN CAST('$end_date' AS DATE) AND CAST('$start_date' AS DATE))";
    }

	    if( !empty($args['scope']) && $args['scope']=='next-week' ){
		$now2 = time();
        $start_date = date('Y-m-d',strtotime('monday  next week', $now2));
		$end_date = date('Y-m-d',strtotime('monday  next week + 6 days', $now2));

        $conditions['scope'] = " (event_start_date BETWEEN CAST('$start_date' AS DATE) AND CAST('$end_date' AS DATE)) OR (event_end_date BETWEEN CAST('$end_date' AS DATE) AND CAST('$start_date' AS DATE))";
    }

    return $conditions;
}
}

add_filter( 'em_get_scopes','my_em_scopes',1,1);
function my_em_scopes($scopes){
    $my_scopes = array(
        'this-week' => 'This Week',
		'this-week' => 'Next Week'
    );
    return $scopes + $my_scopes;
}

Any idea where the bug can be?

Thank you!
