I appreciate the initial steps you've taken, @ali820. I'm here to provide an additional troubleshooting guide to rectify the file attachment in QuickBooks Online (QBO).
Since you have already tried other steps and are still experiencing the same issue, I recommend performing basic troubleshooting to determine if it's a browser-related problem. Sometimes, a browser may be filled with frequently visited pages, leading to certain unexpected behaviors. To address this, open your QBO account in an incognito window to ensure the program runs without storing cache files. You may use these keyboard shortcuts:
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Microsoft Edge: Ctrl + Shift + P
- Safari: Command + Shift + N
If this works, clear your cache and cookies to update any website preferences that might interfere with the program's functionality. If not, you can switch to a different supported browser that is compatible.
You may also want to refer to this article to help you identify the supported file types and learn how to attach a document using these supported files: Add or Delete attachments in QBO.
Also, I'll add this article to assist you in avoiding any special characters in your company name or the names of list items: Acceptable characters in QBO.
Please let us know if you have questions about file attachments. I'm here to help. Take care.
