The two most common reasons are

1. You have another plugin active that adds components to the tinyMCE editor in your WP Admin Write screen. Sometimes these incorrectly assume that the TinyMCE editor can not be used on the front website and thus do not code it properly. It is usually an easy fix but only you know if you have such a plugin.
2. Alternatively – You have a JavaScript conflict – your wp theme or another plugin – which needs to be fixed. This codex article explains what this means and what to look for:

These are, as I say, the most common issues.

Greetings,

First off I love the Simple:Press forum plugin and while I am a relative novice I am not a noob.  I have developed my own WordPress e-commerce site successfully. 

I too am having the a similar problem as indicated above.  Where I believe the settings are correct to activate the TinyMCE editor for topics and posts but the TinyMCE editor is not displaying – only the text editor is.  One of two possible plugins could conflict with the editor, one Meks Flexible Shortcodes is now deactivated but I get the same result.  The second, InstaBuilder plugin for developing custom landing pages, I am reluctant to disable to test for a conflict as my site has not launched and my “under construction” page was developed using this plugin.  It is a premium plugin so I should be able to go back to the developer if there is a problem with their code according to your guidelines for a Javascript conflict.  But truthfully I am unable to determine if is there is a legitimate conflict in the code per your guidelines, see lines 63 & 64.  I had planned on using their plugin to develop other pages but if it is conflicting with your plugin I may seek other options or seek a solution with them.  I have included a PasteBin link to the code for the page I am having trouble with could you please review it for conflicts and give advice on a possible resolution?

Hard to check but as far as I can see that looks good. The next stage is to use the browser’s built in script console and look for errors on page load.

it would be good to see the page source from a forum topic page (ie list of posts) so we can see all the tinymce code loaded…

often themes or plugins add buttons to tinymce but do it incorrectly… they assume the wp editor is only loaded in the admin, but the wp editor api fully supports loading it on front end too…

have you tried a temp switch to the default wp theme and see if any diff?  and potentially try it with other plugins deactivated…

OMG I am a noob – no more than a noob a super noob – I completely missed the profile option to turn on the TinyMCE Editor in the test member account I was using.  I thought I had modified the setting but obviously NOT.  Only after I disabled all the plugins but yours did I realize it must be something I missed in the settings. 

You guys have a great product and thanks Mr Papa for your gracious help on a non-existent problem!

What a complete NOOB i am – LMAO
