Cannot switch to Visual Editor and Upload Media does not work

If you haven’t discovered any PHP errors, and you’ve tried different browsers, maybe a javascript error could be causing the issues you’re seeing? If I disable javascript in my browser when I’m in the editor, I can’t switch tabs in the editor, either. Insert media still works, but without the pop-up, so I may be way off.

If I were you, I would install the Firebug extension in Firefox, enable the Firebug console, and see if your site is throwing any javascript errors when you try to use the features that are broken for you. Almost any javascript error will keep other javascript from working correctly, and I don’t think it would show up in WordPress debugging since it’s client-side.

I’m getting the following error when I firebug the editor:
TypeError: d is undefined
I don’t know what else to provide to someone cause now this is language that I don’t understand.

That may be it. Unfortunately, javascript errors aren’t as specific as PHP, but it tells you that you definitely have an error coming from somewhere.

Does Firebug tell you what file and line number the error is coming from?

Also, take a look at this thread.

wp-includes/js/quicktags.min.js.?ver=3.5 (line 1)

is what it’s saying

I am still having the same issue too. It happened after the 3.5 upgrade. I can’t follow the directions in that thread and am totally frustrated. I keep having to custom build links and insert images with HTML…. it’s taking forever!

@alison – sorry to hear you are having difficulties, but these forums really work much better if you start your own thread per the guidelines.

I’ve been following several threads related to the same issue. I can’t find one that has a resolution that I can actually follow or fix myself. I believe this is at least the second time that skichic95 has posted about this issue. Is another thread really going to fix it?

i have the same issue, i have tried many different ways, now just realize that is related specified themes. the theme Twenty Eleven
and Twenty Twelve do work, but the theme Max Magazine and Asteroid don’t work.

The theme does not matter on my end. Still have the same issue irregardless.

@alison this is the first post on this topic that I have made in this forum. I posted a similar post in the studiopress forums but it was finally ruled that it wasn’t anything related to studiopress…and that I should come post in the wordpress forums.

@skichic95 let’s see if we can figure this out. I have a working version of 3.5 and it looks like you are using WordPress 3.5 so we may be able to figure out what is different. I’m willing if you are.

When you get that kind of error in javascript it can mean:

1. Another script is causing a conflict with it. This is the most common cause with core WP scripts in my experience.
2. There is an error in the script itself.

To rule out number one, we can compare the javascript scripts that you are loading with what one of my installs that’s working is loading. You could use a file-comparison program like Meld to do this quickly for the longer sections of code. To do this, go into the admin side and Posts -> Add New in Firefox. Then hit Ctrl + U to view the source code (or Tools -> Web Developer -> Page Source). Here’s the javascript on my site.

If you’re loading any other javascript than those, or the javascript you’re loading corresponding to those differs other than in the UID or the domain name, then you may have found the source of a conflict. Let me know what you find.

If that doesn’t find the culprit, the next thing to do would be to see if we can find an issue with the actual code. To troubleshoot that, rename your wp-includes/js/quicktags.min.js and save the following (the contents of my working file) as wp-includes/js/quicktags.min.js, then clear your browser cache and re-test:

If that doesn’t work, the next thing is to see if we can get a better idea of what the actual error is, which a minified file makes very difficult. To force WP to load the non-minified versions of the javascript files it uses, go back to your wp-config and add:
define('SCRIPT_DEBUG', true);
Log out of WP. Clear your browser cache (Ctrl + F5 in Firefox) and log back into the admin side of WP. Repeat the steps you use to see the javascript error in Firebug. If we’re really lucky, it won’t happen in the non-minified version of the script, but if it does, we should get a more helpful error message.

Let us know what you find.

My codes aren’t lining up with your codes as far as line numbers. I’m running on a mac so Meld won’t work and the 2 Mac apps that they reference make no sense to me. Is there another way to go about doing this??

I’m having the same problem. I apologize for not being codex literate. I don’t even know where to find those. I don’t understand the instructions for these fixes that are being described here. This is very frustrating. Is there some way to fix this that doesn’t involve rewriting complicated (to an idiot like me) codes?

Don’t worry about the line numbers. I just included them for reference so you can more easily locate the similar blocks of code.

I’m not a Mac person, but the program DiffMerge looks like it would be similar to Meld and allow you to do the comparisons; however, what I would do first is just use a simple text editor with line numbers (so you can get an approximate idea of which code block to compare to) and do a search for “text/javascript” to locate each block of javascript in your page source. See if there are any blocks of javascript that I didn’t list above. If there are not, then you can do the comparisons.
