Updating to Joomla 4

timpennington

I am looking to upgrade from Joomla 3.10.4 to 4.0

Question: should I install the new JA Focus for 4.0 before I install the new Joomla 4.0, or after?

Also, my JA Extension Manager does not show an upgrade to the Joomla 4.0 version, but it is advertised here that it is available. Where do I get the Ja Focus upgrade file if it doesn't show in my JAEM?

Thanks

Hi timpennington You can install latest version of our template and framework before updating J4.

However, the issue comes from 3rd party extension on your site, kindly check this plugin: jssearchjobs

Make sure that it's compatible with J4 first.

Thank you; I can not get access in backend to turn that plugin off right now as the error appears when I go to plugins to disable it. Is there a way to disable that plugin from file manager?

Thank you

timpennington

Update: I was able to disable to jssearchjobs.php file and the backend loaded with no problems.

No I am getting another error on the frontend:

0 Class 'JString' not found

This is at https://imageworx.org/FC4A/

It is not clear on the back end where the error may be coming from.

Thank you for the advice.

timpennington On which page can I see that error?

Thank you; I found that the cause is a 3rd party plugin. I will work to fix that.

Much thanks for all the guidance
