Hello, jp666.

I am also keen and sensitive when it comes to the program's text readability using themes. I appreciate your time in reaching out to our support, but I don't want you to leave empty-handed here. I'll lay down some tools to help you fix the dark mode setting and turn the tables around. 

Have you installed any browser extension that offers dark mode? If this is the case, then this is likely the reason why this mode is always enabled on your end. 

So, we'll want to turn it off by accessing the extensions list in your browser's settings. Each browser is different, so check with their help resources if needed. 

If you're not using any browser extensions, let's take this a little bit further. 

You might've already tried or done this during your contact with the support agent. Is the button to turn off the mode not working? Or is the setting not applying after toggling? 

If you're unable to toggle the option to off, or if the settings are not applying, let's close and re-open the browser to apply the settings.

If that doesn't work, then this is likely caused by a cache-related issue. When a browser's cache is full or corrupted, some settings might not apply correctly. 

To rule this out, let's use an incognito or a private browser: 

• Ctrl + Shift + N  for Google Chrome
• Ctrl + Shift + P  for Firefox
• Control + Option +P if you're using Safari

Check QuickBooks, then turn off dark mode. When you're able to do so, go back to the regular browser and clear the cache. This removes any cache data that's preventing your settings from being applied properly. 

Another alternative is to use other supported browsers. 

After successfully turning off dark mode, we can check QuickBooks again and review the financials if needed. If you need help with this in the future, I'll add this article: Run reports in QuickBooks Online.

I'll hear you out if you have concerns about other settings in QuickBooks. I'll also cover other topics if you need help with reports, entries, and lists.
