Dear friends

Is there any possibility to update this magnificent slider to a new version?

Hi

I use version 5.0.16, and I have to apply some fixes in order to be able to use it without problems, in the newer PHP versions (7.3, 7.4 etc).

Also, the Joomla 4 is almost ready, so I wonder if there will be a newer version of the slider.

By the way, we are a group of friends (developers) here in Greece and we are great fans of the unite revolution slider!

Keep up the good work.

OK. I send you the two fixes for two different problems. 

1. The first is for the error message on the backend: "An Array was declared as a String"

Fix:

/administrator/components/com_uniterevolution2/inc_php/framework/base-admin.class.php

Change line 45 

From:
private static $arrMetaBoxes = ””; //option boxes that will be added to post

TO:
private static $arrMetaBoxes = array(); //option boxes that will be added to post

2. The second error is malfunctioning in the newer php versions (7.1,7.2,7.4 etc)

Fix:

/administrator/components/com_uniterevolution2/inc_php/framework/db.class.php

Change the checkForErrors function (very likely on line 31) to the following:

private function checkForErrors($prefix = ""){
  global $wpdb;

  if($this->wpdb->last_error){
    $query = $this->wpdb->last_query;
    $message = $this->wpdb->last_error;

    if($prefix) $message = $prefix.' - <b>'.$message.'</b>';
    if($query) $message .= '<br>---<br> Query: ' . esc_attr($query);
    
    $this->throwError($message);
  }
}

Hi, sorry I can't give you access to my server and anyway I have applied these fixes already.

Thnx anyway
