Just updated my old debian Weezy that runs on 1.23 wiki/visualeditor with php 5.4.39 and mysql 5.5.43 to the new debian Jessie, all update was done right, but, now the pages are blank. But, if i launch the editor, content is already here... hurra... but if i previsualize or other stuffs, the page remains blank...
So, i decide to follow an advice given here http://www.mediawiki.org/wiki/Manual:Errors_and_symptoms#All_pages_have_no_content.2C_but_when_editing_a_page_the_wiki_text_is_there and i update my wiki to the 1.24.2 with the visualeditor associated to the 1.24. After doing it all, i run the database update and.... the pages are empty now... Adding the error report it shows me the error below :
Warning: spl_object_hash() expects parameter 1 to be object, null given in /var/www/mediawiki-1.24.2/mediawiki-1.24.2/includes/Title.php on line 184 Catchable fatal error: Argument 1 passed to MediaWikiTitleCodec::__construct() must be an instance of Language, null given, called in /var/www/mediawiki-1.24.2/mediawiki-1.24.2/includes/Title.php on line 195 and defined in /var/www/mediawiki-1.24.2/mediawiki-1.24.2/includes/title/MediaWikiTitleCodec.php on line 567
Any suggestions ?
