I am having this problem as well, any help is appreciated.
When asking for help please tell us your MyBB version.
Admin CP -> Configuration -> Settings -> Clickable Smilies and BB Code
Make sure that Clickable MyCode Editor is on.
Also check in the User CP option: User CP -> Options -> Other Options -> Show the MyCode formatting options on the posting pages.
Are you using a custom WYSIWYG editor? There is usually a problem with jQuery when it comes to these... (
fix)
Nayson has also provided some useful links check them out and see if any of those suggestions fix your problem. The
fourth one outlines the common fixes for this issue.
#edit: This has been fixed
This problem has been solved, to those who are also experiencing this problem, look below;
First of all make sure in admincp>settings My codes are on. If the post format still does not appear, proceed to
AdminCP>Templates & Styles>Templates>YOUR THEME>Ungrouped Templates>headerinclude, replace everything inside with the following;
<link rel="alternate" type="application/rss+xml" title="{$lang->latest_threads} (RSS 2.0)" href="{$mybb->settings['bburl']}/syndication.php" />
<link rel="alternate" type="application/atom+xml" title="{$lang->latest_threads} (Atom 1.0)" href="{$mybb->settings['bburl']}/syndication.php?type=atom1.0" />
<meta http-equiv="Content-Type" content="text/html; charset={$charset}" />
<meta http-equiv="Content-Script-Type" content="text/javascript" />
<script type="text/javascript" src="{$mybb->settings['bburl']}/jscripts/prototype.js?ver=1603"></script>
<script type="text/javascript" src="{$mybb->settings['bburl']}/jscripts/general.js?ver=1603"></script>
<script type="text/javascript" src="{$mybb->settings['bburl']}/jscripts/popup_menu.js?ver=1600"></script>
{$stylesheets}
<script type="text/javascript">
<!--
var cookieDomain = "{$mybb->settings['cookiedomain']}";
var cookiePath = "{$mybb->settings['cookiepath']}";
var cookiePrefix = "{$mybb->settings['cookieprefix']}";
var deleteevent_confirm = "{$lang->deleteevent_confirm}";
var removeattach_confirm = "{$lang->removeattach_confirm}";
var loading_text = '{$lang->ajax_loading}';
var saving_changes = '{$lang->saving_changes}';
var use_xmlhttprequest = "{$mybb->settings['use_xmlhttprequest']}";
var my_post_key = "{$mybb->post_code}";
var imagepath = "{$theme['imgdir']}";
// -->
</script>
{$newpmmsg}
Then make sure to go
Themes>YOUR THEME>Edit Theme Properties>Editor Style
and if you aren't already on Office 07, change it to Office 07.
Thanks.
