gRPG v2 paginator error

[Uridium]

im not familiar with PDO  but im getting this error on the tickets page as well as every other page that uses the paginator

Fatal error: Uncaught Error: Typed property Paginator::$querystring must not be accessed before initializatio

 if ($_GET) {
            $args = explode('&', $_SERVER['QUERY_STRING']);
            foreach ($args as $arg) {
                $keyval = (array)explode('=', $arg);
                if ($keyval[0] !== 'page' and $keyval[0] !== 'ipp') {
                    $this->querystring .= '&'.$arg;
                }
            }
        }

its on line 71 which read as  $this->querystring .= '&'.$arg;

 

any help would be fab

Head up to the object/property declarations and initialise the $querystring property

Find:

protected string $querystring;

Replace with:
 

protected string $querystring = '';

That nearly worked 🙂

then I had another error 
Fatal error: Uncaught Error: Typed property Paginator::$return must not be accessed before initialization

on line 110

which is 

 for ($i = 1; $i <= $this->num_pages; ++$i) {
                $this->return .= ($i == $this->current_page) ? '<div class="pure-u-1-24 disabled"><a class="pure-button button-xsmall pure-button-disabled" href="#" disabled>'.$i.'</a></div>' : '<div class="pure-u-1-24"><a class="pure-button button-xsmall" href="'.$_SERVER['PHP_SELF'].'?page='.$i.'&ipp='.$this->items_per_page.$this->querystring.'">'.$i.'</a></div>'."\r\n";
            }

so back to square one

 

After a long and tedious struggle i managed to fix the script
