Safari Web inspector is blank

Question

I try to use the Web Inspector to debug a remote iOS app.

The 1st time I use the Develop menu, the window does not open.

The 2nd time, the window opens but is empty.

Any idea please?

(macOS 10.12.6)

Answer 1

I ran into this with macOS 11.4 Big Sur, connecting to an iPad running iOS 14.5.1. Using Safari Technology Preview fixed it.

Answer 2

I had the same issue. It appeared after IOS updating. MAC OS System updating helped to me. System Preferences -> Software Update. Hope it helps.
