Resolved RO Payments laat de site crashen bij Joomla 6 / Hikashop 6

Hi Roland,

Op een site met Joomla 5.4.0, RO Payments 8.5.0 en Hikashop 6.1.0 deed ik op mijn test server eerst een upgrade naar Joomla 6. Ook toen werkte alles goed.
Bij een poging om RO Payments 9.0 te installeren crashte de site (rood Oops scherm).
Via de database depubliceerde ik ik de ROP 9 systeem plugin en de site was weer toegankelijk.
Daarna error reporting ingeschakeld, en bij opnieuw publiceren van de systeem plugin kreeg ik:

Error

parent::__construct($name, $uri, $options, $attributes, $dependencies);

$langTag = Factory::getApplication()->getLanguage()->getTag();
$client = $this->getOption('client');

if ($client) {
$this->uri = $client . '/language/' . $langTag . '/' . $langTag . '.css';

De site is in principe meertalig maar alleen Nederlands wordt momenteel gebruikt. Zie jij wat er fout gaat?

Groeten,
