Beta insert media sometimes fails

[mark8barnes]

On 3.5 beta 1, inserting an image sometimes fails, causing a javascript error in a bunch of minified javascript I don't understand (line 467 of load-scripts.php).

Chrome: Uncaught TypeError: Cannot read property 'width' of undefined

Firefox: TypeError: e is undefined

The error seems to occur on any image that are below a certain size. It certainly occurs with images that are 250x250, 200x200 and 200x150.

Glad I found the error report, I am having the same issue since updating to beta1.

If I insert an image into a post when in visual mode and save draft the image disappears.

If I am in 'txt' mode instead of visual mode when saving the draft, then the image stays. Seems to be an issue with the visual editor js

It will be easier for us to track down the bug with a little more information. Could you try reproducing the error after setting WP_DEBUG and SCRIPT_DEBUG to true? I've included instructions at the end of this comment.

If you do manage to reproduce the error, please open your browser's JavaScript console and screenshot the error. If you are using Chrome or Safari, expand the error before taking the screenshot. If you can navigate to the affected code, please take a screenshot of that as well, even if you don't know what it means or if it is minified.

Thanks!

How to turn on WP_DEBUG and SCRIPT_DEBUG

1. Open wp-config.php
2. Find the line that says define( 'WP_DEBUG', false ); — if you haven't changed your wp-config.php file, it should be around line 81.
3. Change the false in that line to true.
4. Right below that line, add define( 'SCRIPT_DEBUG', true );
5. Save

The error only flashes on for a second when I click save draft or publish, then disappears.
Nothing remains in the error logs or console for me to copy and paste. Normally when there is an error I have no problem going into the console and copy paste the error, but like I said, this one shows just for a split second upon submit, then disappears (fixes itself) but the images are always removed. Hope it helps.

Sorry, I forgot about SCRIPT_DEBUG. Attached are two screenshots, the first showing the error in Chrome's console, the second showing the important variables immediately before the error. You'll see it's caused because props.size is set to 'medium', but 'medium' doesn't exist in attachment.

Same here, just upgraded to 3.5 beta 1 and I can't add images to posts.

Beta Media doesn't work at all, the old function adds the image to my post, but as soon as I save the draft or publish it, the image is gone.

Same error as Mark's, in Chrome Trace Stack. Tried with IE9, same behavior. No other errors are shown with DEBUG mode enabled, other then the JS error.

I can't even switch to HTML mode in TinyMCE, while the image is being displayed in Visual mode (before saving the draft).

I disabled all my plugins and renamed my functions.php, but it didn't help.

Could this bug be related to #21776 ?

Thanks for the screenshots, mark8barnes, they were quite helpful. This bug was fixed in [22140].
