Hey there, accounting686.
Thanks for bringing your question forward here in the Community. I'm happy to provide some info so you're able to save attachments for projects and jobs in QuickBooks Online.
As an initial troubleshooting step I recommend clearing the browser cache. The cache is in place to collect frequently used data to make loading web pages quicker and easier. If the cache becomes too full it can potentially cause certain viewing and performance errors within the system. Clearing it will remove anything that's preventing the page from successfully saving the attachment. Here's how to get this done in Chrome for example:
- At the top right, select the More ⋮ icon.
- Select Settings.
- Select Privacy and security.
- Select Cookies and other site data.
- Select See all cookies and site data.
- Type “intuit” in the search bar to find Intuit cookies.
- Select Remove all shown or the trash can icon.
- Restart Google Chrome for the changes to take effect.
The following article provides similar steps depending on which browser you're using: Clear cache and cookies to fix issues.
Please give this a try and then save the attachment once more. Let me know how things look afterward. I'll be here if you have any other questions.
