Recently I installed MediaWiki 1.23 version on Oracle enterprise linux 6 and it's working fine. The issue is with the WYSIWYG_1.23/CKeditor editors. I tried configuring both the editors but neither of them worked. I added the below mentioned code to LocalSettings.php file:
require_once( "$IP/extensions/WYSIWYG-CKeditor-CKeditor_v4/WikiEditor/WikiEditor.php" );
require_once("$IP/extensions/WYSIWYG-CKeditor-CKeditor_v4/WYSIWYG/WYSIWYG.php");
$wgGroupPermissions['registered_users']['wysiwyg']=true;
$wgGroupPermissions['*']['wysiwyg'] = true; $wgDefaultUserOptions['cke_show'] = 'richeditor';
$wgDefaultUserOptions['riched_use_toggle'] = true;
$wgDefaultUserOptions['riched_start_disabled'] = false;
$wgDefaultUserOptions['riched_toggle_remember_state'] = true;
$wgDefaultUserOptions['riched_use_popup'] = false;
$wgFCKEditorExcludedNamespaces[] = NS_MEDIAWIKI;
$wgFCKEditorExcludedNamespaces[] = NS_TEMPLATE;
$wgDefaultUserOptions['usebetatoolbar'] = 1;
$wgDefaultUserOptions['usebetatoolbar-cgd'] = 1;
$wgDefaultUserOptions['wikieditor-preview'] = 0;
$wgDefaultUserOptions['wikieditor-publish'] = 0;
as suggested in some of the forums but it did not work. Can anyone help me in resolving this issue? Thanks in advance!!
