Can't load my own pages with .htaccess protection

Question

It's very strange.
First time I noticed that problem was on a project page who I created. The page is not for the public access, so I decide to protect it simply with an htaccess file and it works without any problems for a long time in Safari until that point who I make a little mistake by typing the username or password and let Safari safe this wrong information. Since them I was not longer able to reach the page with Safari, but still with other browsers.
So I can life with that, because it's not an importend page who I visit each day.
But now I have a nother page who deliver the same problem. The logininfos are safed by Safari and no longer access since two days now. Before it works perfect.
The only real change who I do was to fix the permissions of a folder inside the Safari resources. The "German.lproj" folder. I do this, because I was not able to open the private settings in Safari. Each time who I click in the settings on the private option, Safari crashes. Anyway, since I add my profile to the permissions Safari works fine.
I can't belive that this change is the source for the problem. I try to delete all related pagestuff in my keychane of OS X Snow Leo (10.6.8), repair the keychane and repair the permissions over the Disc Utility. I also remove my complete Safari profile in the Library to reset Safari, delete the preferences, delete Safari with Clean App and reinstall it, but still can't access my pages with a htaccess protection.
All other pages working without any problem. All the pages are still available with other browsers.
Anyone an idea what I can try next?

Answer 1

OK, after a long time I solved my problem with the htacces and password protected pages.
But let me explain a bit more, why it need so much time.
After I post here at the board, I solved the problem over a simple resetting of Safari over the menu. After I do that, I got the login-window back.
But for some strange reason I got the problem back after a longer time. And now I got the idea to look a bit deeper, what can happen. I open my Console from OS X and take a view on "All announcements". Now I hit enter in Safari to open the page who have a htaccess protection and I got some error results. On of them was this here:
22.01.12 15:48:32
Safari[1062]
Unable to read contents in the Interface Builder file at path /System/Library/PrivateFrameworks/Safari.framework/Resources/German.lproj/Authe nticationPanel.nib due to error: Die Datei „AuthenticationPanel.nib“ konnte nicht geöffnet werden, da Sie nicht die Zugriffsrechte haben, um sie anzuzeigen..
This message contain some german infos, so let me translate the last part.
The file „AuthenticationPanel.nib“ can't be open, because you have not the right permissions.
This error message looks like the big goal for me. I open this file-directory and mark the "German.lproj" folder to open the information panel for this folder. Now I go to the permission area, hit the "plus" button and add my profile / user to the permissions with a read and wrote permission. My new settings I transfer to all subfolders.
Now the final test in Safari. I open the URL again and, tadaaaa, it works very well now.
This is the same solution who I do before (see my first text on this posting) for the german.lproj folder. It looks like that Apples software like the Disc-Utility ignore the german folders around fixing the permissions or after an update or if you have trouble with the permissions.
Anyway... This two manual fixings bring my access back and I'm now happy :-)
