Hi,
After updating to 3.8.10 on Joomla 4.3.1 on several sites some add-ons fail to load on the backend. I've experienced this with the add-on 'Header' (see screenshot), but on another site it was the add-on 'Clients'.
For now I downgraded tot 3.8.9 and the issue is fixed.
Can you deliver a fix for this in 3.8.10?
