Hello There,
Thank you for reaching out regarding the issue with your "References" page following the update of your website from Joomla 3 to Joomla 5.
Upon investigating your concern, I can confirm that this issue is not related to any JoomShaper product. As my colleague Paul mentioned, the problem arises from a custom override in the file:
html/mod_articles_category/referenzen.php
The template you are currently using is not a JoomShaper template. Therefore, the issue likely stems from compatibility problems with this override and the updated Joomla version. I recommend contacting the template author for assistance in resolving the problem, as they will be best equipped to address the compatibility adjustments required.
Thank you for your understanding. If there’s anything else I can assist you with, please feel free to let me know.
Best regards,
Shuvo
