Safari in Lion not displaying site's header copy...

Robert,

I think you might have solved this for me. Nothing else has seemed to work consistently but by reviewing the Console logs, I found the sandbox error you had mentioned. It seemed the consistently offending fonts were versions of Verdana and Arial in my FontAgent Pro font folder. Once I deleted those fonts from those folders, the problem has not reappearred. Keeping my fingers crossed that this keeps working. Thanks.

I think Robert has provided the best description of the problem so far:

To confirm my situation:

Nothing to do with font-format, happened to PS, TTF, OT

Clearing caches might fix temporarily, but not permanently.

adding

(home-subpath "/Documents/Font Library") ;; that's my path, yours may vary

to /System/Library/PrivateFrameworks/WebKit2.framework/WebProcess.app/Contents/Res ources/com.apple.WebProcess.sb

has fixed it.

The reason it seems to affect people using font managers more is that they are more likely to keep fonts outside of the sandboxed paths allowed.

If adding the path to your font-managed folder in the way described up a few comments is too scary, then I guess the alternative is to move all your manged fonts back into the default font folder, but that may cause problems too.

Tobystokes:

Where exactly do you add this line in the WebProcess.sb file?

I'm also having this issue and it is frustrating since I use Safari for all my web browsing and have no real interest in going to Firefox at this point. I may attempt Robert's fix.

So far, I have used OnyX to clean the font caches. This requires a restart. Once restarted, Safari will work for about a day and then the font issue will return. This is not good.

SYT, insert it after line 61 (home-subpath "/Library/Fonts").

It actually doesn't matter exactly, anywhere between 23 and 81 is fine.

Updating my post from last week (fixed issue after cleaning system/user fonts with Onyx) I continue to have no problems, despite adding and activating many fonts daily via both Fontbook and Suitcase Fusion. I have also re-restarted four times since Onyx fix.

I've finally fixed the issue for me!

I was having the same problem after installing Lion, I tried cleaning all the font caches with onyx but that didn't help for long.

In the end I disabled all my fonts in FontAgent Pro. The fonts have slowly been activating as I open more files in InDesign. Today I opened a book I'm working on and the problem started again.

Because I only have a few fonts activated in fontagent pro t it was easy to see which was the problem by disabling them one by one.

The problem font for me was ArialMT, if activated in fontagent pro I would get the A boxes, with it disabled it's fine!

I've deactivated and deleted the font from FontAgent Pro so fingers crossed this fixes the issue.

Good luck ... I've had several false moments of thinking I've fixed this due to Helvetica, Tahoma, Arial, Verdana fonts - and currently have those disabled - but the issue still creeps up for me eventually.

No other apps are giving me this grief - or other browsers, it's pretty much just Safari. Just when I think I've resolved the problem, a day or so later, it happens all over again.

This is really annoying for a web designer.

It was Helvetica Neue for me. Ever Since I upgraded to leopard all those years agao, every time I started up I'd a get a Helvetica Neue warning dialogue. This persisted through Snow Leopard and then last nigth, after installing Lion, I had the dreaded symbols y'all are talking about. Really annoying as I'd moved from Safari to Chrome (and wanted to go back as Safar now seems to run lightning fast). Anyway, went into Font Explorer and found that in my Helvetica Neue folder I had a load of blue system versions (note, nothing got highlighted as a conflict which was annoying also), so i turned off the duplicated fonts and viola....all works fine in Safari now.

Here's what my Helvetica Neue Folder now looks like:

Hope that helps some.

Regards

Steph

John -- Have you checked your Console log for mentions of fonts?

I have, for instance it's happening right now on some parts of Twitter, but the errorr log shows nothing as being wrong. No errors, warnings, no mentions of font family.

John, it's nothing to do with any font in particular, it's to do with where the font files are kept. You can see what fonts should be being displayed by using the web inspector - and i bet you those fonts have been moved out of your Library/Fonts folder, by FontExplorer or another font manager.

The simple fix is to put them back in there and only use Fontbook as a manager. If you don't like that, you can follow the instructions to hack that WebProcess file, above.

Well I tried the hack fix, and no it didn't work for me. I didn't move any of the base System fonts - I let Suitcase Fusion leave the system fonts alone where they should be.

and sorry, but being a hard core full time graphic designer - using Fontbook just isn't an option - it's nowhere near as robust font manager as I need.

John, I agree.

FB is not an option for designers or printers.
