Joomla 3>4 Cannot access protected property Joomla\CMS\Menu\MenuItem::$params

Asked by Peron 3 years ago Last activity 2 years ago

Hi,
I migrated to joomla 4 and get the following message on the frontend:
Cannot access protected property Joomla\CMS\Menu\MenuItem::$params
I use the ultimate template.
Even though a lot of people seem to have this problem with a lot of different templates and for quite some time, you dont seem to provide a solution on the support forum.
Is there anything I can do by myself, correcting scripts or something?
That was the first migration I tried and I have some more to come with other templates ( spectrum, shaper_salon...)
Thank you for your help
Peron

  • Spectrum - is Helix3 based template.
  • Salon - is Helix Ultimate based template.

In general I agree with you that it shouldn't be like that. Hopefully everything can be fixed in 90 seconds, after template update to current version. As you can read in the above guide.

Enable Debug and preview again, you should see more about source of error

then inform me or get know which file you still have to override.

I have the same problem with the SHOPIN template. Can you help me?

In Helix3 based template you have to override all files from raw Helix3 template/quickstart

Focus on those two folders! Use FTP tool to override files 

templates\shaper_helix3\html\mod_menu --> templates\shaper_shopin\html\mod_menu 

templates\shaper_helix3\features  --> templates\shaper_shopin\features

I don't understand, should I replace just these two folders or everything?
Fino ad adesso ho sostituito solo le due cartelle indicate ma non funziona e l'errore è sempre lo stesso.

YES, just override those 2 folders (only those!) - as I said
