Hi,
we have been using for quite some time the JA Smallbiz Template on our Joomla 3.10.11. page and didn't have any issues with the template style administration in backend so far.
We then kept updated the templates and its associated modules and plugins with the JA Extension Manager so that we always have the latest supported releases.
In the recent past we have performed updates again and just realized that the Template Stile Administration page looks now weird and does not longer have the known user interface.
See screenshots
Please note that we are currently in the process to perform a migration of our site to Joomla 4 and newer PHP versions.
We have installed a fresh version of Joomla 4.3.1 with JA Smallbiz and are migrating one by one our components and data.
On this new Joomla 4 page we have exactly the same issue with the template and it also looks same as on current production page with Joomla 3. So there is something very strange with JA Smallbiz and it does not longer work same way as it did in the past.
Can you please take a look. I have provided access to the Joomla 4 backend but can also provide access to Joomla 3.
Regards
Markus
