Updating Kunena 6.3.4 from 6.3.3, the message editor (ckeditor) becomes hidden.
I examined the reasons and found that the line 38 of the
components/com_kunena/template/aurelia/layouts/widget/editor/ckeditor.php
was the cause.
I modified the line 38, from
$this->doc->addScriptOptions('com_kunena.ckeditor_joomladefaultlanguage', substr($joomlaLanguage
color=#ff0000]3[/color, 0, 2));
to
$this->doc->addScriptOptions('com_kunena.ckeditor_joomladefaultlanguage', substr($joomlaLanguage
color=#ff0000]0[/color, 0, 2));
, and Kunena comes to work properly.
My site runs with the Japanese translation.
With '$joomlaLanguage
color=#ff0000]3[/color', the line generates
<script type="application/json" class="joomla-script-options loaded">... "com_kunena.ckeditor_joomladefaultlanguage":"
jp", ... </script>
but with '$joomlaLanguage
color=#ff0000]0[/color',
<script type="application/json" class="joomla-script-options loaded">... "com_kunena.ckeditor_joomladefaultlanguage":"
ja", ... </script>
So I guess this bug may be concerned with the translation mechanism.
