Cannot access protected property

chrodos

Hello, we have a problem with our website after upgrading to Joomla 4.

We use JA Teline V, the site is multilingual (English and Greek). Only on the Greek site, I have the following error:
Cannot access protected property Joomla\CMS\Menu\MenuItem::$params

When I changed the template to the default "Cassiopeia" the error was removed.

Hi chrodos

Could you share the URL + admin account of your site? I will check for you.

chrodos

saguaros

Unfortunately, we can not. It is an intranet site.

saguaros

chrodos You can go to Backend >> Global Configuration >> and enable Debug System option.

Then refresh frontend page, it will show the detailed of the error and share it with me.

chrodos

saguaros

It is already enabled the Debug System

saguaros

chrodos It's hard to guess with just this message. You can take a backup of your site via Akeeba backup extension and share me the backup file via: sales@joomlart.com , I will restore site in my local and debug for you.

Hello, we didn't get your reply.

Did you have an issue with the VPN access or the website access and login?

I have checked the website login information and there is no problem.

Why did you send an email? Did you find any problem with the vpn connection?

I am very disappointed, we are talking about this issue for the last 2 months without any progress.

chrodos I had issue with vpn connection, could you simply take a backup of your site with Akeeba backup component and share me the backup file? I will restore in my local and check for you.
