Solved it.
There is a file in xoops_data/caches/xoops_cache/_editorlist
1378607743
return array (
'textarea' =>
array (
'title' => 'Plain Text',
'nohtml' => 1,
),
'dhtmltextarea' =>
array (
'title' => 'DHTML Form with xCode',
'nohtml' => 1,
),
'tinymce' =>
array (
'title' => 'TinyMCE',
'nohtml' => 0,
),
);
Changed nohtml to 1 for TinyMCE.
Now, I don't know if i want to use this editor. Isn't it a high security risk to allow your users to post html?
