Asus RT-AX3000 (RT-AX58U) All tabs disappeared from all pages

[wrapperNo1]

Today, for some reason all tabs from all pages are not showing anymore. I tried rebooting, restarting power, reflashing the latest firmware, with no avail.
I have Diversion on an external flash drive, it's still working, but I can't access its tab in the interface, and I'm assuming the drive is not corrupted since it's still working. There was a power outage earlier today, not sure if it's the cause. What can I do?

Welcome to the forums @wrapperNo1.

Clear your browser cache, try with incognito (or equivalent) mode. Use a different browser.

If the same result, power off the router and remove the USB drive. Power up and test (all above) again.

If this is a USB 'key' and not an external enclosure with an SSD inside, it is probably toast.

Thanks a lot L&LD. I'm dumb. I did already tried clearing site data, and didn't work. Didn't think about testing incognito, which worked.
Solved!
