I just did a fresh installation, details below, and I'm getting a blank home page. If I view the source I see basic HTML header lines and an empty body. I looked in the archives and it seems like this might be a bug with 1.8.2, but I'd rather get some feedback before going to the hassle of downgrading. I moved LocalSettings.php as required. Win Server 2003, IIS6, PHP5, MySQL 4.1 The other installation details are (**** obscures some details for security): PHP 5.1.6 installed Found database drivers for: MySQL Warning: PHP's register_globals option is enabled.

Why is PHP's register_globals option is enabled??? Thats rather unsafe, any person has access to MediaWiki's source code, If they find one mistake in the way vars are handled they could get your admin password using an xss exploit? As far as the page not working, what is the page you expect to work? site.com/wiki/index.php is error reporting turned on in php.ini if index.php exists it should atleast throw some errors? The only other thing I can think of is did you modify MonoBook.php? or index.php in some wierd way? I had added a html comment under the </html> tag on my MonoBook.php file once and it gave me simular trouble to what you have: sometimes only page headers would be sent, no page content. Chris

You need access to somthing like "/usr/local/lib/php.ini" do you have ssh access? If you mess with the index.php file like add some html to the top <h1>test</h1> does it show up? If it does try writting some bad php at the top <?php aaa ?> does this display the correct error msg? You really need to figure out where you have problems, is it the php install, is it the wiki install is it apache, etc ... Figure out what does and doesnt work on your system, do other php pages load correctly, are errors being reported when there is a problem etc.. A blank page is a really hard problem to access. Any one else have any ideas? Chris On 1/8/07, Robin Faichney <robin(a)robinfaichney.org> wrote:

Yup

According to phpinfo() error_reporting = 341, otherwise error_* is "no value". Can I change these using my own php.ini in the root folder? If so, what are recommended values? I haven't made any changes at all to the out-of-the-box mediawiki setup. -- Robin Faichney The Invisible Eye on Consciousness <http://www.robinfaichney.org/> _______________________________________________ MediaWiki-l mailing list MediaWiki-l(a)lists.wikimedia.org http://lists.wikimedia.org/mailman/listinfo/mediawiki-l

No, and it's a shared machine.

I guessed this might be the same problem as Jan was seeing, ie this behaviour from 1.8.2 while all other versions work fine, so I tried 1.7.1 and it works. I'm going to stick with that for now. Thanks anyway. -- Robin Faichney The Invisible Eye on Consciousness <http://www.robinfaichney.org/>

Haphazard guessed workaround based on the most common problem people are having with 1.8.x for "no apparent reason": Set $wgDisableCounters = true; in LocalSettings.php. If this works, then the problem should be fixed in the 1.9 branch, 1.9.0rc2 is available now. Rob Church

Yes, seems so. Downgrading to 1.7.1 helped :) I think, Brion now identified the reason with the Zend Optimizer.

In the last days this bug seemed to be fixed in the 1.9-svn-trunk, so in the upcomming 1.9 release this will be fixed. This this bug: http://bugzilla.wikimedia.org/show_bug.cgi?id=8439 1.9 will be release today or tomorror ... in the notes you will find: === Zend Optimizer === A bug in some versions of PHP 5 and Zend Optimizer which was triggered under MediaWiki 1.8.x has been worked around by disabling some internal debugging features when Zend Optimizer is loaded. This should solve some common "blank page" problems. Regards, Jan

Hi Jan, having looked at the bug report it now seems this is not the same problem after all, because I get valid HTML back, with head and body tags but no content. I might try 1.9 anyway just to see what happens, and if so I'll report the result here. Wednesday, January 10, 2007, 10:27:30 AM, Jan wrote:

You've tried the workaround I suggested? If so, and it didn't fix it, then check the PHP and Apache error logs for relevant lines. If there are errors there, but you don't understand them fully, just post them here and someone is bound to fire back a diagnosis. Rob Church

You must have missed my previous message in which I said I'd downgraded to 1.7.1, which worked for me. I've now tried 1.9rc2, which also works. You'll understand I'm not about to go back to 1.8.2 just to find out why it didn't work! -- Robin Faichney The Invisible Eye on Consciousness <http://www.robinfaichney.org/>
