Let’s access your QBO company through a private or incognito window, ajeethd.

This helps isolate the issue since it doesn’t store data in the cache. Make sure to use correct login credentials. Here are the keyboard shortcuts: 

• For Chrome, press Ctrl + Shift + N.
• For Internet Explorer or Firefox, hit Ctrl + Shift + P.
• For Safari, hold down Command + Shift + N.

Then, try to delete the custom template again.  If it works, let’s clear the cache of your regular browser. This helps the browser to function efficiently. You can also use other compatible browsers if the private browser doesn’t work.

If you have any other concerns, please let us know.
