WP 4.7.3 Database Problem – wowslider/list-table.php on line 239

I’ve approximatively the same problem. The alert on WP is:

Warning: Declaration of WOWSlider_List_Table::single_row($id, $data, $index) should be compatible with WP_List_Table::single_row($item) in /volume2/web/mybees/wp-content/plugins/wowslider/list-table.php on line 0

same problem her i hope for a fix

Me too have this problem, how to fix it????

If you set WP_DEBUG to ‘false’ in wp-config.php file. These do not affect your website.

Bot the problem is that above does not work sometime.
That can happen on cheap/shared hostings that force displaying PHP ERRORS, warnings and notices.
In that case, you can remove this line from your wp-config.php file:

define('WP_DEBUG', false);

and place this:

ini_set('log_errors','On');
ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

in my case its working.

We changed it on this way. It works ??

\wp-content\plugins\wowslider\list-table.php Zeile 174, 169

function display_rows(){
$index = 1;
foreach ($this -> items as $data){
$this -> single_row($data[‘id’], $data, $index);
$index++;
}
}

function single_row($id, $data, $index){

–>

function display_rows(){
$index = 1;
foreach ($this -> items as $data){
$this -> single_row($data[‘id’], 0, $data, $index);
$index++;
}
}

function single_row($id, $level = 0, $data = array(), $index = 0){

I tried the later proposition and it didn’t work.

But I’ve to say, it’s quite complicated and it’s possible I made one or more mistake by copying. Than I had to copy back my saved files (don’t forget to do it before trying this solution).

Does someone else made a better experience than mine?
