The URL: arkana.freeall.org/arkanapedia It's in Hebrew... The version of MediaWiki is the latest. I downloaded it this week. 1.5.5, I think. Version of PHP - 4.4.1 (according to control panel of the host) MySQL version - 4.0.25-standard Apache version - 1.3.34 (Unix) Operating system Linux Kernel version 2.4.21-27.0.4.ELsmp Machine Type i686 PERL version 5.8.4 It's been installed for about a week, I've done it through the automatic configuration - Uploaded it through FTP, ran the appropriate file, checked Hebrew and that's about all of it. It never worked OK. Now, it finally saves the pages, but only after that message that keeps coming. I haven't done any customizations except editing some pages and changing the logo link at LocalSettings.php That's about it... Nothing of what you said doesn't sound right, except from "something broken"... Because - I haven't changed any code, and couldn't be any mix cause the installation is completely new, on a clean server... Well, Thanks for anything! Peleg. ----- You still haven't provided basic background information such as: * the URL to your site * version of MediaWiki * version of PHP * version of anything else * how long it's been installed * how you installed * whether it worked before and stopped working, or never worked * if you've made any customizations to the configuration The SearchUpdate class is defined in SearchUpdate.php, which is included from UpdateClasses.php, which is included from GlobalSettings.php, which is included long before this code is reached. So, this shouldn't be possible unless: * Something's broken * The code was altered * There's a bad mix of files from different versions, etc -- brion vibber (brion @ pobox.com)
