Hello, please activate the backward compatibility plugin.

That should help.

so no then lol
i have been told that selecting backward is not a good idea moving forward.

Sometimes you have to take a step back.

just as long as the templates will be eventually ready for 6 lol thanks

This worked for some of the templates, but for others I still get this error message:

500
BEHAVIOR::CAPTION NOT FOUND.
An error has occurred while processing your request.
You may not be able to visit this page because of:

500 behavior::caption not found.

Only the templates Nina, Emani, and Layla are ready to run on J6 (with the J6 compatibility plugin enabled). The rest of the Joomla51 templates work under J5 (with the J5 compatibility plugin enabled) at maximum.

Dear Dautrich,

that's not entirely correct. Only these three templates are marked as Joomla 6 ready. However, other, even older, templates already work under Joomla 6. I tested it with several templates in a test environment. I would also wait for an official release from Ciaran.

But whether that will happen...

I know that this is only the “official” statement from the Joomla51 website. A Joomler from Switzerland has adapted Chelsea to run under J6, even with the J6 compatibility disabled. Yesterday, I did the same job for Skylar. And just a few minutes ago, I saw Emani running under J6.

Obviously, there are J6-compatible versions of Joomla51 templates running “in the wild”. But how to cope with the situation? Will Ciáran Walsh eventually return and solve the issues? I'm in doubt .....

BTW: Modifying the templates' code is not illegal, because the PHP code is distributed under GPL. But the CSS and JS files are copyrighted according to the comments in the code. Should we provide the adapted versions to a customer of Joomla51 within certain restrictions (i.e. only after he provides a screenshot of his account at the Joomla51 site, proving that he has purchased the respective template)? I don't know.

What needs to be done to make a template run under J6, even with J6 compatibility disabled?

I would be very interested in this workaround. Is there a source for this?

Best regards

First, you have to make sure that the template is J5 native (meaning not needing the J5 compatibility plugin). To do so, you have to exchange any appearance of a deprecated class with the new J5 class:
- Prepare a (local) dev site.
- You find the complete list in the developer documentation of Joomla here
- Visual Studio Code is very helpful to find and replace all occurences.

Example:
- You find an occurrence of JFactory like this

$user    = JFactory::getUser();

- You can replace this either with:

 $user    = Joomla\CMS\Factory::getUser();

- Or you can put a use-statement right at the beginning of the file (after the defined('_JEXEC') or die; ) like this:

use Joomla\CMS\Factory;

with this, you can shorten the statement to:

$user    = Factory::getUser();

Repeat that for all old classes in all php files of the template. VSC helps you by showing the class names in a different color like that:


It's a tedious task, but it took me only about one day including testing for one template (Skylar).
Be aware that this is not a real refactoring of the code, but just the minimum task to get things going.

And the good news: After that activity, the modified template works under J6 with the J6 compatibility plugin disabled.

Sorry, double post.
