Hi Brion, thank you for answering.
MediaWiki 1.3.3 is giving strange error-messages on pages with thumbs, but only when I use the browser Netscape 7.1 and not with IE 6.0 or Firefox 0.9. The error messages are the following:
Those messages have to do with your PHP configuration and shouldn't be affected by which browser you use. It's possible that there's a caching issue that causes Netscape to see different versions of the page, or the error messages might be hidden or displayed differently (check 'view source').
I can observe the difference between Netscape 7.1 and Firefox 0.9 even in the source code. So I think you are right, it might be a caching issue of Netscape 7.1, because there is nothing wrong in the other browsers.

Well, that's going to make it pretty hard to shell out to ImageMagick.
If you're unwilling or unable to change that, try using the GD library support instead (switch the settings in LocalSettings.php). This of course will only work if GD support is available in your PHP configuration.
I allready disabled ImageMagick this afternoon, but may be the error messages are still present (in Netscape) due to the caching issue you mentioned.
Warning: stat() [function.stat http://www.php.net/function.stat]:
Stat failed for /www/htdocs/v101777/wiki/images/thumb/5/57/180px-Kvdr-image02.jpg (errno=2 - No such file or directory) in /www/htdocs/wiki/includes/Image.php on line 246
It's also kind of odd that there are different path names here. Is this a deliberate configuration you've set up, or something weird?
I am sorry, this is my fault: I wanted to erase the directory name and forgot this one ;-)
The thumbs are working well (with GD library support), so I hope the error messages will dissapear once the cache is reloaded.
Thank you! Markus
