Update to joomla 4 - 'Module by zero' error

spinosimarketing

Hello,
we are testing the upgrade to joomla 4 on a development domain
We use the Uber template on the site.
The static pages work, while the ones with featured articles, like the home, give error 'Module by zero'.

We have many other sites where we use Uber and where we have upgraded to Joomla 4.

Compared to the other sites there is something strange about the Uber update, in fact the custom template does not update to 3.0 (see img 01).
While on other sites the custom template also updates (see img 02).
Probably something has been done on the files, but since it is a site we inherited from others we can't pinpoint the problem.

Thanks

spinosimarketing Could you share the FTP account of your site? I will debug and see what's wrong here.

Hi @spinosimarketing

The fact that you've been modifying the template without updating it for a while has led to outdated files within your template.
The error you mentioned arises from a file you modified, which is /templates/ltform/html/com_content/featured/default.php (there may be other errors due to the outdated template as well).. Your cloned template needs to be compared and updated to version 3.0.0 (the current version you are using is 2.1.8)

Ok, got it.

Is there any way to automatically check which template files have been changed from the original?
Once identified the best thing is to overwrite the template with version 3.0 and then redo the changes that were there?

Thanks again

Hi @spinosimarketing

You can use file comparison applications to work more efficiently. For instance, you can use the WinMerge application for this task.
