I suggest doing some troubleshooting steps to ensure the script error pop-up won't show anymore, Barry.

Since, you're using a 2017 version of QuickBooks Desktop pro, here a steps for you to follow in fixing this error:

1. In the search box next to the Start menu icon, type Control Panel.
2. Click the Control Panel. A page will appear on the Start Menu under the Best Match title.
3. At the top of the control panel window, type change in the search box.
4. Under the Program & Feature section title, select Change or remove a program.
5. Locate the QuickBooks installation you want to repair, and then double-click it to launch the installer.
6. When the QuickBooks Installer/ Maintenance Wizard launches, click Next to see the options Repair and Remove. Select Repair and then click Next to complete the process.
7. Once completed, restart your computer, even if Windows does not prompt you to do so.

Also, I'd recommend reaching out to an IT professional for guidance about the script error.

Refer to this article for guidance in creating a backup of your company file in QuickBooks Desktop.

Install the trial version for Desktop 2018 or 2019. Did you encounter the same problem?

I got the identical script error when opening my co file. QB freezes when I try to receive inventory and I have to crash with task manager. After several attempts, QB couldn't open the co. file at all (6123,0).  File Dr couldn't repair, Windows installer couldn.t repair. I've reinstalled Premier 2015, but the same problem. File Dr. now tells me hosting mode is off and QBDBMgrN is not running on my computer. Norton 360 is active, but is allowing all QB through the firewall. https://a166211981.cdn.optimizely.com/client_storage/a166211981.html is a blank page with a white background.

Which Windows OS do you run?

I'm having the same issue. Even went back to restore old Backups which in the past have eliminated this error, but doesn't seem to be working this time.

Thanks for joining this thread, jelizondo.

If you've already performed the troubleshooting steps in RhoiceW's post, but you're still encountering a script error, I'd recommend getting in touch with our Customer Care team. They'll be able to pull up your account in a secure environment, conduct further research with you, and create an investigation ticket if necessary.

They can be reached while using QuickBooks.

Here's how:
 

1. In the top menu bar, go to Help, then QuickBooks Desktop Help/Contact Us.
2. Enter a question, keyword, or topic you need help with.
3. Select Contact Us.

Be sure to review their support hours so you'll know when agents are available.

If there's any questions, I'm just a post away. Have an wonderful Thursday!

Windows 11 Pro was installed about 3 months ago - the script error started popping up a few days ago.

Which Windows OS?

I have the same problem as well.  Since we aren't getting updates from QB anymore this must be a new conflict introduced by a Windows or another update?  Has anybody found a fix for this issue or is it time to upgrade my QB Desktop?

I'm using QB Desktop Pro 2018 with Microsoft Windows 10 Enterprise on a Dell Latitude 5430.

Cheers,

Jeff

Solution

-Block the offending URL in your windows hosts file-

-Edit hosts with notepad.exe as administrator-

Add the following line

# Block access to a url in a startup Quickbooks script that results in an error

127.0.0.1 a166211981.cdn.optimizely.com

Mike, are there any negative consequences with Quickbooks if this URL is blocked?

To answer my own question, if you Google "what is cdn.optimizely.com" you will see what a content delivery network does.  From my reading it looks like it caches web pages to improve Quickbooks performance and allows for A/B testing of web pages.  If your use of Quickbooks doesn't need web pages, my guess is it is safe to block this URL.  Maybe Quickbooks mistakenly, or purposefully, discontinued the use of this Optimizely CDN.

I am running the 2013 Desk top version of Quckbooks.   This worked for me, but I also had to shut down quickbooks and re-start my Windows P.C. for the update in the host file to take effect.  Once the page is blocked, the script that no longer runs on it doesn't run....   no more error.

Let me add... shame on quickbooks for sending us to some third party crap without our knowledge or permission.
