WYSIWYG / CKEditor - Unable to save and edit that includes a website link

Help / Discuss
,
#1

I’ve been looking at this for 2 days. Everything on the XWiki site is great but when I go to edit a page and put a website link in the page it won’t save and errors with:

Failed to savethe page. Reason: Server not responding

Even if I take the default Home page and simple edit it with WYSIWYG and just and a single word and click save, samething. But if I chnage to Wiki or Inline form I can edit the page and save it with a website link. Only WYSIWYG / CKEditor fails to save when a page contains a website link.

Any insight you guys have would be great! I’m a little new to XWiki and I have everything I want/need in place except this one thing and without it I can’t share it with the team or put it in production.

Here’s some more details on the errors I get when the save fails.

DevTools failed to load source map: Could not parse content for http://xwiki01:8080/xwiki/bin/jsx/CKEditor/Translations?sourceMap=true&minify=false&language=en: Unexpected end of JSON input

prototype.js?r=1:1739 POST http://xwiki01:8080/xwiki/bin/save/Main/ 400

In the Network debug for the Edge Browser I get:
http://xwiki01:8080/xwiki/bin/save/Main
HTTP Status 400 - Bad Request

Apache Tomcat/9.0.64
I am using a Windows Server w/Tomcat.

From personal experience:

May be you have a problem with UTF-8 characters.

UTF8-characters are represented by 1,2,3 or 4 bytes.
If you use a MySQL database which is not “utf8mb4” you will get this kind of error if you entered a 4-byte character.

I also have this issue, except its with the standalone version running on Jetty and the internal database (HSQLDB). I have made absolutely no changes to the config or any files … its exactly as downloaded from the xWiki website… I can save URLs on a page when I use the ‘Wiki’ editor…but if i try and save a page with URLs using the WYSIWYG editor, I get the error.

Log gives me this …

org.xwiki.rendering.parser.ParseException: Failed to parse input source

The fact this occurs on the untouched vanilla standalone version makes me wonder if its an issue with the JAVA install/version? …

PS C:\Websites\wiki> java -version
java version “19.0.1” 2022-10-18
Java™ SE Runtime Environment (build 19.0.1+10-21)
Java HotSpot™ 64-Bit Server VM (build 19.0.1+10-21, mixed mode, sharing)

I have the same issue on Windows Server 2016 as well as Windows 11… Both are set to United Kingdom Region

If I look in the browser console at the 400 error, I see this…

Request URL: http://localhost:8080/xwiki/bin/save/Main/
Request Method:POST
Status Code:400 Bad Request
Remote Address:[::1]:8080
Referrer Policy:strict-origin-when-cross-origin

Did you manage to resolve your original issue, and if so what did you have to do?

Facing the same issue myself. Running a vanilla test environment on Windows 10 with Jetty and can’t save any pages that use links .
