Hello for the first time.
Recently I updated my mediawiki from 1.4 to 1.5.8. Did everything the upgrade guide said.
First I backed up the database and the wiki/ directory too. Then I replaced everything except LocalSettings.php, images/ and extensions/, with the correct permissions. Created the AdminSettins.php, ran maintenance/update.php and refreshLinks.php. At last, php -f rebuildMessages.php rebuild, because I had everything in "es" (like Portada instead of MainPage). Now, the problem is that every article shows a "?" sign instead of the correct non-english character, like accented vocals or Ñ. The content is in spanish, so there are a lot of words like this: "?rbol" instead of "árbol".
You can see it here: http://linux.mty.itesm.mx/wiki/
What can I do?
If you need more info please ask.
Thanks for your time
