Solved Error Messages after J3 to J4 upgrade

I followed the steps outlined in the docs (in J3 uninstall Kunena, plugins and in J4 install Kunena 6.25, plug in, etc.

I am seeing these error messages:

1. Front End (Any Kunena Menu)
0 Cannot use object of type stdClass as array

2. Backend (Template page) - Aurelia is the only one visible to choose from.
The Joomla\Http\Transport\Stream transport is not supported in this environment.

Any ideas where I should be looking to figure this out?

I am using a Gantry 5 template (Rocketheme) if that helps.  Advise if more info is needed.

Thanks in advance.

I was able to resolve the backend admin error message. My web host enabled "allow_url_fopen".

The first still appears on the front end. Debug mode indicates the following:

Rendering Error in layout Widget/Announcement: Cannot use object of type stdClass as array in /home/.../components/com_kunena/template/aurelia/layouts/widget/announcement/default.php on line 27
Layout was rendered in /home/.../libraries/kunena/src/Html/KunenaParser.php on line 140

AND

Rendering Error in layout Announcement/Listing/Row: Cannot use object of type stdClass as array in /home/.../components/com_kunena/template/aurelia/layouts/announcement/listing/row/default.php on line 35
Layout was rendered in /home/.../components/com_kunena/template/aurelia/layouts/announcement/listing/default.php on line 111

I cannot access the Report configuration settings and getting this error:  "An error has occurred: Object of class stdClass could not be converted to string"

Any idea what the error might mean?

 

Hello,

Did-you right checked to set Aurelia as default ?

Yes in fact that is the only template available when I installed Kunena

After to have installed Kunena 6.2.x, did-you go to the Kunena dashboard ? And did-you see the messages that the tables of Kunena has been updated ?

I don't recall. Should install/reinstall to try again and see if I get that message?  [UPDATE - I reinstalled and saw this error message when I accessed the dashboard
