After i've upgraded MW 1.4.3 to MW 1.9.0 all text marked with <pre> is rendered as UNIQ<big hexa number>QINU
Also other Wikimedia tags are replaced with same pattern (examples: <nowiki>) What can mess up Wiki parser?
You have broken extensions that have not been updated for the new version, and/or the system is broken generally. Confirm the correct files are uploaded and in use. Recache pages.
I'm having the same issue after upgrading from MW 1.7.3 (without any extensions) to 1.9.3 using the update.php script. To double check I have created a new 1.9.3 wiki with source files from SVN - and the problem is just the same. Gentoo Linux, MySQL 5.0.32, PHP 5.1.6.
By the way: Not only existing pre-tags are replaced. I create a new page on a virgin 1.9.3 install, add something like "<pre>this is a test</pre>" and hit save. Result: Something like "UNIQ41a56c0d8438eb5-pre-00000001-QINU" instead of the pre-tagged content. Other tags such as div are working just fine.
Check your php.ini conf ; Enable compatibility mode with Zend Engine 1 (PHP 4.x) zend.ze1_compatibility_mode = Off When it is set to On in PHP 5, MW parser goes crazy.
That's it, big thanks for this hint!
It would be really usefull to find a solution for people like me who cannot access to php.ini. I have installed MediaWiki: 1.9.3 and have the same problem of Sven Schwyn.
Try to upgrade to PHP 5.1 or upper. Citing from http://www.mediawiki.org/wiki/Manual:Upgrading_to_1.9#Check_requirements: <blockquote> Note: PHP 5.0 has bugs on 64-bit systems which cause fundamental problems with MediaWiki. If you are running on an x86_64 (AMD64, EMT64) or other affected 64-bit platform, you must run PHP 5.1 or higher. </blockquote> I'm not sure that it will work, but I've PHP 5 and the pre and nowiki tags are rendered correctly.
Sorry, that's a really bugged-up switch in PHP which should never be used. We can detect it and warn the user, but that's it. Contact your hosting provider for information on how to change PHP settings via .htaccess or otherwise.
