Hi Ciaran

I am not quite sure about the correct way to update a Joomla 3 website with a J51 Template to Joomla 4.
Should I install the J51 Joomla 4 template before or after updateing Joomla?

Thank you and kind regards
Chris

Hi !
I don't know what Cirian advises you but basically you should have done some other things beforehand to do this migration. The template is just one thing.
In case you are unfamiliar with these important steps. Here are some links that can help:

Hi

thank you very much for your kind hints. In fact my request concerns the updating process for the J51 template only. I am very familiar with the updating process of Joomla 3 to Joomla 4.

I tried both methods but either of them was unsuccessful:

Method a)
- Install the J51_Template_J4 over the existing J51_Template_J3 in Joomla 3
- Then start the Joomla Update process

Here I get a «500 behaviour::caption not found» error on any page.

Method b)
- Update Joomla 3 to Joomla 4
- Then install the J51_Template_J4 over the existing J51_Template_J3

Here the home page was ok, but any other page produced a «500» error.

A new installation with the J51_Template_J4 was ok. But here all previous template settings are lost.

So I got the impression, that it is not possible to upgrade from a J51_Template_J3 to J51_Template_J4.
Unless Ciaran has an idea.

Kind regards
Chris

ok !

As far as I know, only the last three templates are capable of Joomla 4 (Nina, emani, Layla)
The others are still to come. so it is described here in the forum and in the templates...

What is your template?

J51_Nina.
On Joomla 3 I had J51_Nina_J3, then I bought J51_Nina_J4.

I think I found a solution. It seems to be working. But I am not sure if this is the way that Ciaran would recommend.
I would like to preface saying that I am doing this work with a copy of the live website, not with the live website itself. At least making a backup before beginning is strongly recommended.

- Install J51_TemplateName_J4 in the Joomla 3 version of the website
- Do not be surprised: the frontend will now produce an error message
- Complete any other checks and steps that are necessary before starting the Joomla update
- Update Joomla 3 to Joomla 4
- The frontend will still produce an error message
- Delete any files and folders from /templates/j51_TemplateName/... except a possibly existing custom.css
- Install again J51_TemplateName_J4
- Now the frontend works fine now and the template settings from the Joomla 3 website are respected

The aim of my procedure is to keep the template settings that are stored in the database. And then it seems as if there are some old files somewhere in /templates/j51_TemplateName/... that are not overwritten by installing J51_TemplateName_J4. That's why I deleted the whole path and reinstalled the template. I have had a good experience with it.

Kind regards
Chris

Hi Chris

I would personally suggest installing the Joomla 4 version of the template after you update your installation to Joomla 4 but ultimately it will not make any difference to the end result. One thing I would suggest before updating is to rename your ../template/[YourTemplate]/html/ folder to html-backup. We have seen some issues where this folder is not updating correctly. Renaming the html folder first will resolve this issue and why your described solution most likely works.

I tried this procedure and now my back end area where I control the settings for the styles looks like a mess (see screenshot).

Any ideas how to fix this without losing my styles and settings?

Hello

It appears your template admin is still loading the old CSS. TO amend try doing a full refresh in your browser (CTRL + F5).
