Thread:Project:Support desk/Upgrading from 1.21 to 1.22mwf12 on Hebrew wiki

Hi, I want VisualEditor on my Wiki, so I'm trying to upgrade it to 1.22mwf12. I have some 30 pages in Hebrew (mostly with a lot of paragraphs).


 * MediaWiki: 1.21.1
 * php: 5.3.27 (cgi-fcgi)
 * mysql: 5.1.68-cll-lve

I have downloaded 1.22mwf12 from https://toolserver.org/~krinkle/mwSnapshots/#!/mediawiki-core/wmf/1.22wmf12 Unpacked it to a new folder and copied the LocalSettings.php file. Called php /maintenance/update.php file to update the db, and the output seemed ok.

When I tried to access the wiki, no page was found, and all titles changed from Hebrew or urlencoded hebrew to ??????????????????? When I accessed the same database from MediaWiki 1.21 it all worked as usual, without touching the db.

Any ideas as to why this is happening? How can I fix it?

Thanks
