Hello there, @Tabby1. Let's perform some troubleshooting steps so you can open QuickBooks Online (QBO) and access payroll using a Safari browser on your iPad. 

Based on your description, it seems that you have a corrupted or damaged webpage data due to the browser's collection of files over time from frequent page visits. 

To log in to QBO and make your payroll work using a Safari browser on your iPad, I encourage you to clear your cache or history and cookies. This will refresh the system and remove older data that causes viewing and performance issues. Here's how:

1. Go to Settings.
2. Select Safari.
3. Tap Clear History and Website Data.

You can also refer to this article to learn more about deleting cache and Intuit-specific cookies to quickly fix issues when using QBO: Clear cache and cookies to fix issues when using QuickBooks Online.

However, in case the display error persists, I'd recommend using other supported browsers.

Also, you may want to check out one of our Help pages as your reference in managing your payroll account and employee transactions using QBO Payroll: QuickBooks Payroll Support. It includes QuickBooks help articles, Community discussions with other users, and video tutorials, to name a few.

You can keep me posted on how it goes in the comments below. If you have other payroll concerns or questions about managing your QBO account, I'm always ready tp help. Take care, and have a great day, @Tabby1.
