Hello Chris,

You may consider using Joomla 3.10 for the already created themes but if you would prefer to move to Joomla 4, here are some tips to re-create the theme:
- organize controls in Sections and use Export as Zip option in the Section tab, then import them in a new theme using Import as Zip
- there are Export / Import options available in the Posts tab to transfer Posts layout and styling

Sincerely,
Nettie

Hello Chris,

Unfortunately, we cannot use themes for Joomla 3 for the websites with Joomla 4. The theme should be re-created and based on a separate theme from our Downloads page - the one for Joomla 4.

Nettie

Hi Nettie,
sorry but I didn´t get it.
Seems that I was able to upgrade Themler to vers. 559.
I cannot change the template, because the site is online.

Many thanks !
Chris

Hello Chris,

There is a separate theme for Joomla 4 on our Downloads page. To see the update, you may need to switch Beta update notification setting in your profile. Then the Updates sign will be present when you open the theme.

Hi Nettie,

the path in the upper windows (127.0.0.1:12080/themler_4176362660/joomla/...) is indeed looking on a side with joomla 4.
We thought, that we can use Themler for several sides with different joomla versions ?

Cannot find the Update to version 559 ?

Many thanks !

Chris

Hello,

Could you please consider updating the theme to v.559? Looks like your Themler version doesn't support Joomla version used on the website. Or do you use Joomla 4?

Nettie

Hi Nettie,

seems that it is Themler 441 an d it doesn´t connect because of

Fatal error: Call to undefined method JApplicationAdministrator::isClient() in C:\ProgramData\Themler\hd_data\themler_4176362660\joomla\plugins\system\helix3\helix3.php on line 44

We use several Joomla Versions and PHP versions....

Best regards

Chris

Hello Chris,

Do you use the latest Themler v.559? Could you please specify your Joomla and PHP versions?
