New Web Inspector for Safari

The new Web Inspector was made to be a bit closer to Xcode.

There is no direct way to get the old one back, without reverting to other means. For example:

• running Lion in a VM (to run an older Safari).
• Running a nightly build of WebKit - but this may only have the new inspector
• Using Chrome (while still WebKit, it still uses something that seemed closer to me like the old inspector).

So no, at this time, it doesn't look like its possible to revert back to an 'older' version of the inspector. The best bet would be to submit bugs at http://bugreporter.apple.com. If it is missing features that the old one had, possibly future revisions would bring some of this back.

I have just fixed precisely the same problem on a site. Its annoying when a debugger chokes so it can't help you find the problem!

My problem was caused by a stray class making its way into a style.

<div style="background: #ffb380; padding-bottom:30px; width:300px; text-center;">

Removing the text-center fixed the problem and web-inspector loads correctly. I would expect you also have an error in the page that is causing web-inspector to choke. Two approaches I can recommend:

1. An online error checker e.g. http://www.onlinewebcheck.com/
2. Track down the issue by removing content from the page until web-inspector loads.
