The xwiki edit page is blank

This is expected. Unfortunately “Load JavaScript Skin Extensions” doesn’t work well with the standalone WYSIWYG edit mode, see Loading... . You should keep this option unchecked (which is the default). Note that the in-place WYSIWYG edit mode is loading the required JavaScript skin extensions regardless of this option, so you can use that for existing plain wiki pages. For creating new pages and for structured pages (TextArea properties) you’re forced to use the standalone WYSIWYG editor though, so you need to leave with the fact that JavaScript is not loaded inside the editing area.

Hope this helps,
Marius

Hi @mflorea ,

Thanks for the response.

I have other issues came up.

my ubuntu os: 20
xwiki lts : 16.10.2
tomcat9
java 17

since i need to update and when it update to latest 17.10 on ubuntu 20 it does not work. So, i made a plan to upgrade OS to 24.

steps which i performed.

  1. remove xwiki lts repo
  2. update and upgrade and fullupgrade - 22 version
  3. update and upgrade and fullupgrade - 24 version
  4. systemctl stop tomcat9
apt purge -f tomcat9 tomcat9-common
rm -R /etc/tomcat9/

  5. wget https://maven.xwiki.org/xwiki-keyring.gpg -P /usr/share/keyrings/
echo "deb [signed-by=/usr/share/keyrings/xwiki-keyring.gpg] http://maven.xwiki.org lts/" > /etc/apt/sources.list.d/xwiki-lts.list
apt update

  6. apt install -y xwiki-tomcat10-mysql
  7. commented <Connector port=“8080” protocol=“HTTP/1.1” section in /etc/tomcat10/server.xml
  8. added AJP block <Connector protocol=“AJP/1.3” address=“127.0.0.1” port=“8009” secretRequired=“false” redirectPort=“8443” in /etc/tomcat10/server.xml
  9. cat <<EOF >> /etc/default/tomcat10

# IAT xwiki runs headlessly and wants more memory than standard
JAVA_OPTS="\${JAVA_OPTS} -Djava.awt.headless=true -Xmx2048m"

# IAT xwiki install instructions suggest using urandom for better performance
JAVA_OPTS="\${JAVA_OPTS} -Djava.security.egd=file:/dev/./urandom"

# IAT xwiki use UTF-8
JAVA_OPTS="\${JAVA_OPTS} -Dfile.encoding=UTF-8"
EOF
  10. superadmin andxwiki.store.migration=1 changed in /etc/xwiki/xwiki.cfg
  11. systemctl daemon-reload
systemctl restart tomcat10
systemctl restart apache2

reverseproxy apache2 is also there.

Now, wiki boots and does not give any issue until i went into Administer Wiki > Global Administration: Users

its ldap users but the page is loading and does not show anything. eventhough users can login without issues

For this, see Attachments live data - Attachemnts list loading / vue 3 upgrade issue? - #7 by mflorea . For the rest, I suggest you open a new topic. Mixing various topics is not going to help you in fixing your problems.

Hope this helps,
Marius

update:

I have upgraded the following and current environment is as follows:

Ubuntu 20 → 24 - current
Tomcat9 → Tomcat10- current
Xwiki → 17.10.4
Load JavaScript Skin Extensions → unchecked

Firefox → editor works - No blank Pages

Realtime error still happen → can’t access property “language”, y.document is undefined - prompt for few seconds.

I have went to https://domain/xwiki/bin/view/XWiki/Realtime/Configuration#History and rolled back to Version coming from extension Realtime UI 17.10.4.

Rollback to version xar:org.xwiki.platform:xwiki-platform-realtime-ui/17.10.4 	Current version

still it gives the same error. I also tried to rollback to oldest version and still same error. e-g

Install extension [org.xwiki.platform:xwiki-platform-realtime-ui/15.10.14]

Answer to the Question: The xwiki edit page is blank - #10 by mflorea

I have wrote a text and it does show under the logo on left side top of the page.

in object editing of Configuration →

Objects of type XWiki.StyleSheetExtension (1)
StyleSheetExtension 0:
New StyleSheetExtension object
Objects of type XWiki.UIExtensionClass (8)
UIExtensionClass 0: org.xwiki.platform.template.header.after.realtimeConfig
UIExtensionClass 1: org.xwiki.platform.requirejs.module.chainpad
UIExtensionClass 2: org.xwiki.platform.requirejs.module.chainpad-netflux

UIExtensionClass 11: org.xwiki.platform.requirejs.module.nacl-fast
UIExtensionClass 12: org.xwiki.platform.requirejs.module.nacl-util

How can i troubleshoot it? Please guide me through step by step. which things i need to touch.

Thanks

Hi,

I found the solution. as Can't access property "language",A.document is undefined - #7 by shiraz post has the same problem as this. “realtime” we have two options.

  1. Deactivate Realtime:
    Goto>Administer Wiki>Editing>WYSIWYG Editor>Deactivated Plugins> search xwiki-realtime and select it> save.
  2. Activate Realtime:
    These steps we need to follow. Reason I found we use AJP and websockets are required by realtime. so we need to enable the http connector in tomcat10 which send the trafic of websocket to apache2 and apache2 can handle websockets.
root@xwiki:~# nano /etc/apache2/sites-enabled/default-ssl.conf


# 1. Enable Rewrite Engine
RewriteEngine on
# 2. Detect WebSocket "Upgrade" header and redirect to Tomcat HTTP port
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteCond %{HTTP:Connection} upgrade [NC]
RewriteRule ^/xwiki/websocket/(.*) ws://127.0.0.1:8080/xwiki/websocket/$1 [P,L]
# Route WebSocket traffic to the HTTP/WS port
ProxyPass "/xwiki/websocket/" "ws://127.0.0.1:8080/xwiki/websocket/"
ProxyPassReverse "/xwiki/websocket/" "ws://127.0.0.1:8080/xwiki/websocket/"


root@xwiki:~# nano /etc/tomcat10/server.xml

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" 
           address="127.0.0.1" />
		   

root@xwiki:~# nano /etc/xwiki/xwiki.properties

websocket.ssl.enable = true


root@xwiki:~# nano /etc/xwiki/xwiki.cfg

xwiki.url.protocol=https


root@xwiki:~# sudo a2enmod proxy_wstunnel

Considering dependency proxy for proxy_wstunnel:
Module proxy already enabled
Enabling module proxy_wstunnel.
To activate the new configuration, you need to run:
  systemctl restart apache2


root@xwiki:~# systemctl restart apache2.service
root@xwiki:~# systemctl restart tomcat10.service
