CKEditor cannot instanciate.

This is the code :

            this.editorInstance = CKEDITOR.replace(this.htmlElement, {
                language_list: ["ar:Arabic:rtl", "fr:French", "es:Spanish", "en:English"],
                disableNativeSpellChecker: true,
                removeButtons: "Subscript,Superscript",
                extraPlugins: "colorbutton,print,font,autolink,justify",
                removePlugins: "sourcearea,maximize,image,stylescombo,scayt,wsc,elementspath,blockquote,link,specialchar,resize",
                title: this.title,
                readOnly: false,
                resize_enabled: false,
                autoGrow_minHeight: 200,
                autoGrow_bottomSpace: 50,
                autoGrow_onStartup: true,
                toolbarStartupExpanded: false,
                toolbarGroups: [
                    { name: 'others' },
                    { name: 'clipboard', groups: ['clipboard', 'undo'] },
                    { name: 'editing', groups: ['find', 'selection', 'spellchecker'] },
                    { name: 'links' },
                    { name: 'insert' },
                    { name: 'forms' },
                    { name: 'tools' },
                    { name: 'styles' },
                    '/',
                    { name: 'basicstyles', groups: ['basicstyles', 'cleanup'] },
                    { name: 'paragraph', groups: ['list', 'indent', 'blocks', 'align', 'bidi'] },
                    { name: 'colors' },
                    { name: 'document', groups: ['mode', 'document', 'doctools'] }
                ]
            });

Expected result

There should not be an error. There was no error with CKEditor 4.6.2 :

Actual result

There is no property "fr" on c, there was one in v4.6.2.

The result is the following error :

Hi,

I'm not able to reproduce described situation. Can you check my example (which work fine on my computer) and tell is this problem also occurs here? https://codepen.io/msamsel/pen/EXoagM?editors=1010
If not, then could you prepare some live example or describe more details how to reproduce this situation?

[ghost]

Hi,

The problem doesn't occur on your example.

The problem doesn't occur anymore on my app (i didn't test since this bug report), i don't know why. The only change since i post this bug is Chrome (it has been updated to v 59.0.3071.115).

I think you can close this bug.

Thank you for the time you spent on it !

[msamsel]

You're welcome :)
I'm happy that everything start to work fine in your app.

[kattianita]

@msamsel - What did you have to do? I am using Angular 4.2.3 and Angular CLI and I am getting the same error messages.

[msamsel]

Hi @kattianita,
unfortunately Angular integration is not provided by CKEditor Team. As far as I know there are some community setups which provide integrations between Angular and CKEditor. You can try check stack overflow for some help or advice, maybe someone had similar problem already.

If you are able to reproduce error with clear HTML + CSS + JS environment, please provide detail steps how to obtain such error. Another option which might be helpful is to use not-minified version of ckeditor. You can download this repository and use it you project. This should give you more descriptive error message.

@kattianita to solve this problem in my angular 4.x app I simply added the CDN to the head tag in my src/index.html file.

<head>
  <meta charset="utf-8">
  <title>{{ title }}</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.png">
  <script src="https://cdn.ckeditor.com/4.5.11/full/ckeditor.js"></script>
</head>

[morteza-gho]

I encountered this error when I concat ckeditor.js file with other js libraries!
When attach ckeditor.js separately, everything is OK!

[nasiruddin-saiyed]

This happens when ckeditor.js is integrated from angular-cli.json.

"scripts": [
        "assets/ckeditor/ckeditor.js"
      ],

Its works well if its removed from angular-cli.json & declared in index.html.

<head>
  <script type="text/javascript"  src="assets/ckeditor/ckeditor.js"></script>
</head>

[iczabalegui2h]

This problem is presented by not placing the language script in the file index.

<head>
<script type="text/javascript"  src="assets/ckeditor/lang/en.js"></script>
<script type="text/javascript"  src="assets/ckeditor/lang/es.js"></script>
<script type="text/javascript"  src="assets/ckeditor/lang/fr.js"></script>
</head>

Then, they should confirm that all the tags are in the scripts.
Regards!

[mariohmol]

@kattianita had issues with angular as well..

including the language worked! <script type="text/javascript" src="assets/ckeditor/lang/en.js"></script>

thanks @iczabalegui2h

[lucascco]

In my project I just had to put the script with full-all

<script src="https://cdn.ckeditor.com/4.5.11/full-all/ckeditor.js"></script>

[msamsel]

Some of above issue was related to inserting CKEditor inside Angular. From good news I can say that we currently working on Angular integration with CKEditor4. You can get some details about it here: #2481

[Amir2828]

Anybody had this problem and solved it when integrating with React?

[f1ames]

@Amir2828 Do you use official CKEditor React integration? If so could you report your issue in the integration repository?

[Amir2828]

@f1ames I didnt use the CKEditor for react.

I have a React Project which contains a grapesJS section.
I would like to include CKEditor inside my grapesJS.
There is already an available plugin ( 'grapesjs-plugin-ckeditor'), which says I have to install CKEditor manually, So I did.
But for some reason CKEditor give me the problem mentioned above.
I imported CKEditor via import statement.

[simaosoares]

I'm facing the same issue after building my AngularJs app with gulp.
I wonder if there is a solution for build tools like gulp where all the required vendor files are merged into one single file.

Ckeditor seems to use a relative path to load it's required files from the source folder.

Thank you

[f1ames]

@Amir2828 this issue is not reproducible with CKEditor 4 instance itself so it seems it is an integration issue. You may try to reach out to grapesjs-plugin-ckeditor authors to see if the issue is related to their plugin.

@simaosoares there are few external files which are loaded by CKEditor even in build CKEditor version and this files should be present where CKEditor looks for them. You may change the path by altering CKEDITOR.basePath.
There is also an official CKEditor 4 Angular integration which should solve this issue so you may consider switching to it in your application.

[Amir2828]

At The end I used a CDN link and I made it work, couldn't make it work with npm for some reason

For others with this problem, if you have self-hosted the CKEditor script in your solution (for example for a classic ASP.NET application) and you do not have all the localization files of the plugin in your CKEditor folder, that can cause this issue to happen.

We for example only had the en.js file in our /CKEditor/lang/ folder, and the bug occurred when a user that had both english and danish as his browser languages. CKEditor tried to automatically set the language of the editor to Danish, and tried to load the /CKEditor/lang/da.js file, which did not exist (which caused a 404 error). Adding the following to the config.js file fixed the problem for us:

config.language = 'en';

@kattianita had issues with angular as well..

including the language worked! <script type="text/javascript" src="assets/ckeditor/lang/en.js"></script>

thanks @iczabalegui2h

yes !! including the language worked!

It's worked, Thank you so much!

[EthanStandel]

Just wanted add my two cents for Next JS. I was just testing the component out so I was doing it on a /ckeditor route using a /src/pages/ckeditor.js. Turns out that breaks it, creating the same error 🤷

[TrevorLoney]

I was having this exact error message.

Turned out to be when the library loaded the relevant language files "ckeditor\lang\en.js"
it was adding a timestamp to the request (to prevent caching errors I assume) ie. ?t=G14E

I was serving the files from a dinky little nodejs server that was not handling the requests properly.
So the lang file was not being found and settings were missing causing the issue.

Adding a line to strip the querystring to the server fixed the issue.
