Hi Simin,
Glad to hear from you again. Dealing with error messages can be a strenuous experience but don't worry, I'm here to help. QuickBooks is carefully designed to help automate most of the manual tasks involved in your accounting. This saves you time for the things you enjoy doing.
First, I'd like to start off by troubleshooting this issue to determine if it's a browser related issue. Clearing cache and cookies is a great way to clean your browser allowing it to work more efficiently. Here's an article which shows you how to do that: How to clear cache and cookies. If this doesn't work, I suggest using a private/incognito window to see if that works instead. Try this out and let me know what happens.
If you're still seeing the error, I highly suggest contacting our support team so they can share your screen and help determine what's going on on the account. One of our specialists can share your screen and assist with troubleshooting this further. Here are the contact details:
- Phone: Call us at 1-855-253-1536 from Monday to Friday between the hours of 9 AM and 8 PM EST.
- Schedule a Callback or start a Chat: click (?)Help in the upper right > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
- Social Media: Facebook, Twitter, and Instagram.
My goal is to get you back on track with your accounting. Feel free to ask questions below, I'm here to help. :)
