Let's make sure you'll be able to reply with the post, Anton65.
Normally, you should be able to post in our system without any issues once you're able to log in . You can launch a private window (incognito) and check if you're still getting the same problem. I've provided the shortcuts keys below so you can follow:
- Press Ctrl + Shift + N (Google Chrome)
- Ctrl + Shift + P (Firefox)
- Control + Option + P (Safari)
Once logged in, return to your default browser. Your cache and extensions are probably interfering with the scripts where QuickBooks is trying to run the page. Clear the cache so you'll be able to work with a clean slate. If not, you can switch to a different browser.
Furthermore, QuickBooks provides variety of reports that tells you the aspects of your business. You'll just have to filter and customise them so you'll be able to get the data you need most. I've provided this article for more information: Customise Reports In QuickBooks Online.
Keep in touch if you have any concerns when posting here in the Community. I'll be here to help.
