Timeline widget stopped to show pictures

giorgiofagiolo · 2015-01-15T16:31:18.593Z

Same problem here! The twitter widget embedded in my website suddenly stopped to display images (only a white box with a “click to view on twitter” message). I am on a Mac with OsX 10.7.5 and Safari 6.1.6 (7537.78.2), Chrome and Firefox (both up-to-date). I tried to re-embed the html code with no success. Can anyone help on this? Thanks!

Yep, it’s a problem on Twitter’s side - their platform.twitter.com/widget.js is returning undefined for one of it’s functions - hope they fix soon.

PCNWeb · 2015-01-15T17:57:33.595Z

Note, if anyone at Twitter reads these - the src tag for the image value is returned as “undefined” from platform.twitter.com/widget.js

The Widget was not visited, so settings weren’t changed. The picture is expanded but not displayed (empty frame). However I deleted and created a new widget, same behaviour. If the problem comes from Twitter, why does it work a Wordpress homepage, but not in the forum?

For those of you experiencing problems, would you mind sharing a URL to a page that demonstrates the problem? Or if you cannot do that, an id of an embedded timeline that’s exhibiting this issue would also be helpful.

IE is defaulting to document mode 8 on the landyfriends but is defaulting to edge on the best4x4. That is the issue. Twitter widget javascript for document mode 8 has been removed. I don’t have a solution for this though that I can think of

I have exactly the same problem on the following website:

Photos were working fine up until Wed 14th Jan. Now all photos are displayed as a blank placeholder.

This is the site that is experiencing problems (MBA with OsX 10.7.5 and Safari 6.1.6 (7537.78.2), but also Chrome and Firefox, both up-to-date).

All of the web pages shared in this thread that are experiencing issues are using prototype.js 1.6. That library overrides Array.prototype.reduce with a non-standard implementation which results in widgets.js setting the source of images to undefined.

itbobby · 2015-01-18T15:10:27.257Z

So how do we fix it or is it a twitter side issue? Tks for your help

Updating the version of Prototype used on your site should fix the issue immediately.

Embedded Timeline with Prototype 1.6.0.2:
http://jsfiddle.net/qpbbzhyo/

Embedded Timeline with Prototype 1.7.2.0:
http://jsfiddle.net/2zrkLcq3/

The Array reduce method was removed from Prototype in version 1.6.1 (August 2009).

github.com

sstephenson/prototype/blob/6de3ea468ea09709fe7605c686949430e5912881/CHANGELOG#L160


* Do not use short-hand element methods notation (@element.getStyle() -> Element.getStyle(@element)) for performance reasons. Do not use `$A` and `Array.prototype.shift` when `Array.prototype.slice` can be used instead. (kangax)


* `Prototype.Browser.Opera` now uses stronger inference and is determined by [[Class]] of `window.opera` being - "Opera". (kangax)


* Fix error in event.js which prevented attaching more than one responder for an event name/element combination. [#651 state:resolved] (Rob Lineweaver)


* Do not sniff when testing for IE's proprietary mouseenter/mouseleave events support. Use more robust inference instead. (kangax)


* Use `Prototype.emptyFunction` consistently throughout unit tests. [#253 state:resolved] (Michael M Slusarz, John David Dalton, kangax)


* deprecation extension: mark Array#reduce() as removed. [#569 state:resolved] (Tobie Langel)


* `Form.serialize` now works safely with forms that have "length"-named elements. [#77 state:resolved] (Peter Adrianov, John-David Dalton, kangax)


*1.6.1_rc1* (March 22, 2009)


* `Element#update` now takes care of SCRIPT elements in IE. [#573 state:resolved] (Martin, Tobie Langel, kangax)


* Remove unused local variables from `Element.extend`. Fix one of the form tests to remove `_extendedByPrototype` by setting it to `undefined` rather than `false` (`_extendedByPrototype` being `false` does not force `Element.extend` to re-extend element). (T.J. Crowder, kangax)


* Make test for `escapeHTML`/`unescapeHTML` more strict. (Chrome 1.x escapes "<" and "&" with `innerHTML`, but not ">") (kangax)

Huh…ok…can you give some more help? Seems that I need to edit a file or so…sorry, I’m not a developer…
How do I do what needs to be done…more practically…?

Landyfriends · 2015-01-18T21:16:51.651Z

In addition, there is no prototype.js on my server…
I did a complete file scan.

Hi Niall, thanks for your post, do you mean that we should embed this

script src=“https://ajax.googleapis.com/ajax/libs/prototype/1.7.2.0/prototype.js”

in our html? where exactly? So far I tried without success.

UPDATE:

Thanks Niall, problem solved here. I did not have Wordpress or similar either, just plain website (originally created with iWeb, now deprecated). What I did was to replace the content in the file <iWebSite.js> (which I’ve found in my folder on the server) with the new content copied from https://ajax.googleapis.com/ajax/libs/prototype/1.7.2.0/prototype.js; now et seems to work flawlessly (until the next upgrade I guess!). I hope this may help also others with the same problem: practically what you have to do is to look in your server for a .js file containing the prototype (st starting with “var Prototype={Version:” I guess) and replace the whole content with that in the file https://ajax.googleapis.com/ajax/libs/prototype/1.7.2.0/prototype.js I am not an expert, so probably what worked for me may not apply to others!

Landyfriends · 2015-01-20T11:26:05.056Z

Hello! Any help on fixing that practically…I’m somewhat lost here…

Thanks!

PCNWeb · 2015-01-20T15:55:50.616Z

JakeHarding - I found the old prototype library in the WordPress theme and updated it - thanks for troubleshooting and responding here.

Landyfriends · 2015-01-20T16:53:48.307Z

No Wordpress for me…plain server with Woltlab forum software.
