Missing Visible/Code tab on writting page

Does your browser have javascript enabled. The WYSIWYG editor makes heavy use of it. I’ve also heard a few firefox extensions blocking it, Noscript, Adblock.

Some “security suites” block javascript as well.

Also, check the web server error logs. I’ve seen a couple instances in the past month where it wasn’t working because PHP memory was exhausted.

Thanks to answer.

I don’t have any javascript blocking extension … far more, with other web browsers I have the same issue.

How can I check the webserver error log if I don[t have physical access to it?

Somebody here? I’m having this trouble yet…

I found the way to explore some logs on my server and PHP configurations.

I have seen a 12 MB limit on memory to PHP, can be it my problem???

I’m investigating my problem.

I installed in a local server a wordpress from the same version and yes, I have the HTML editor.

I was searching in the wordpress source code and I found something:

This javascript:

<script type="text/javascript">
	// <![CDATA[
		if ( typeof tinyMCE != "undefined" && tinyMCE.configs.length > 0 )
			document.getElementById('edButtons').style.display = 'block';
	// ]]>
	</script>

It’s on my new post page HTML source and I found it in the ./wp-includes/general-template.php

I don’t know why the javascript tinyMCE is undefinied in my clean clean installation and it works on my test-local installation.

Somebody can help?

The first thing to check is to deactivate all of your plugins and switch to one of the 2 built in themes that come with WordPress. If it works at that point then you have a javascript conflict happening. Activate the plugins one at a time and try to use the editor, if it fails after one of the plugins is activated then that’s the culprit. If they all work then try your theme, if it fails then then it’s your theme. If after deactivating and using the default themes it still doesn’t work it could be your browser (somewhat unlikely though since you said it worked on a local version) or more likely your server configuration.

Make sure you have the latest php 4 or 5 version installed, along with the most recent 4.1.x or 5.x mysql. Also, check your file permissions for your files. It’s always possible that they are set wrong and aren’t being allowed to be read (make sure they are at least 644).

I switched off all my plugins, I use the default theme and nothing. I don’t mind that it’s my browser because you know, oteher installetion in other server works ok.

My server:

PHP version (showed by phpinfo() function): 4.4.7
MySql client API version: 4.1.20
MySql Server version (showed by a phpmyadmin access): 5.0.45-community-log

This is an external server … I can access by FTP, but I can’t configure very many things…

I thing it would be permission problem, but with thins PHP installation I have to put execute permission to very much files and I don’t know what files have to be writable and what don’t

Well, it’s solved…. I don’t know if it would be a permission problem or a wordpress bug… because with the latest version (2.3.1) of wordpress I have the visual and code editors back.

Thanks to all for your help, it’s solved!
