Hi, I updated my website from Joomla 3.10.4 to Joomla 4.0.6 and installed Purity III afterwards, but the template doesn't work. I keep on getting the error message "0 - Cannot access protected property Joomla\CMS\Menu\MenuItem::$params" . It occurs with php 8.0.15 and 7.4 on the following website: https://update.johanneum-hamburg.de/ . Any suggestions?
Regards Til
pimpam Hi Kindly check you are using latest version of the template and T3 plugin. If issue remain same kindly edit field in first post and submit a temp super user login for staff.
Thanks for your quick reply. Both seems to be up to date. I added the user detail above therefore.
pimpam Hi Kindly check the site not using the Session handler from DB and Joomla not running on your current session handler
Hi, thanks for checking. I deactivated the caching so the backend is accessible now.
pimpam Hi Kindly check the website now, the issue is fixed. It was due to outdated version of T3.
Great, thanks for fixing. I thought I was using the current version of T3 since it was downloaded from here 🙂
pimpam No It was pretty older version of T3 on your site.
