Hi,
From what I understand, the Joomla project is currently working on adding an option to be able turn off the dark mode in the next version of Joomla 5.
On our end, we're currently looking into it to support dark mode in the next version of HikaShop, but we might have to wait for the version after the next one.
If you can't wait, you can either:
- use another backend admin template which has an option to turn off the dark mode.
- use another browser (like firefox) which has an option to turn off the dark mode.
- turn off the dark mode in your OS.
