Let's try some steps to resolve the issue, brian22.
If you haven't already, please use a different browser and log in to QuickBooks Online. The browser that you're using might have stored too much data or is having an issue that's keeping you from editing the vendor's profile.
You can use any of these browsers:
Chrome
Internet Explorer
Microsoft Edge
Safari
Mozilla Firefox
You can also delete your browsing history, then log back in. Once done, go back to the vendor's profile and click the Edit button to check if that works. Open this article on how to do that: How do I clear my browser cache and temporary Internet files?
I'm having the same issue. Tried a different browser and clearing the cache. Some vendors I can edit the profile, others I cannot - I get a blank screen.
I have some information to share about getting a blank screen upon editing a vendor or contractor's profile in QuickBooks Online.
We currently received reports wherein customers are seeing a blank screen when editing vendors' information. Our engineers are already investigating the main reason for this unusual behavior, so they can apply a permanent resolution.
In this case, I'd suggest reaching out to our Customer Care Team so you'll be added to the list of the affected users. This way you'll be able to receive email notifications about the recent updates about this issue.
For now, to make your work done, you can refresh the contractors page by pressing F5 on your keyboard or click on your browser's refresh/reload button. This will re-display the list of contractors'.
Thank you for your patience while this has been worked on.
My doors are always open to help if there's anything else you need concerning QuickBooks. Just leave a reply below and we'll take it from there. Have a fantastic weekend!
Thanks and welcome aboard to the Community, @Nealwald.
We have an open ticket about the Edit Vendor button being responsive. Our engineers are finding a complete solution to get this feature working back to normal.
While waiting for the permanent fix, we’ll have to add the company to the notification list. This is to ensure you receive email updates regarding the resolution status.
Here's how:
In your company, go to the Help menu in the upper right hand to open the Search window.
From there, scroll down to click the Contact us link.
