NOTE: TinyMCE 5 reached End of Support in April 2023. No more bug fixes, security updates, or new features will be introduced to TinyMCE 5. We recommend you upgrade to TinyMCE 6 or consider TinyMCE 5 Long Term Support (LTS) if you need more time.
Troubleshoot server-side components
Debug problems with the Enterprise server-side components.Contribute to this page
- Ensure that your firewall has the appropriate ports and rules configured correctly. Be sure that the server the service is running on is accessible from the browser via the port specified in the server configuration
- Check the logs of your Java server for information. When making changes to the configuration you will need to restart the application server each time a change is made for that change to take effect. Refresh your browser window and then try the service again.
If a service does not appear to be working, this is generally caused by one of the following reasons. This guide will walk you through the debugging process to identify the specific problem and how to remedy the issue.
application.conffile is incorrect. Please go back and follow the steps listed in the installation guide. This is the most common problem - often the origins are specified without the port numbers and this can cause things to fail, eg: use
http://localhost. After making changes to the
application.conffile, please restart your Java web server (e.g. Jetty or Tomcat).
application.conffile is correct, but something is wrong with one of the services. See the section below to debug the services.
application.conffile is correct, and the services are working, but the server-side component URLs that the editor uses are not quite right. Refer to the Spell Checker Pro, Image Tools, Enhanced Media Embed and Link Checker plugin pages for help.
- The browser is sending a different origin than expected (and configured in
application.conf). Refer to step 6 of Using browser tooling to investigate services issues
If the editor is reporting that the service cannot be found and tracing the network traffic reveals that no request is made at all, check that the server is not listed in the
Trusted Sites section of Internet Explorer’s security options. If it is, remove it and try again.
If the server is not running on a standard HTTP or HTTPS port (80 or 443) then Chrome will include the port in the Origin header that is sent to the server. Other browsers do not do this. If you have set
false, then you will need to include the port in the
allowed-origins. See Additional Information Around Entering Origins for more details.
Open your browser’s Console/Network tools:
- Firefox: Tools menu -> Web Developer -> Network.
- Safari: Develop -> Show Error Console. Click the Timelines link between Resources and Debugger.
- Internet Explorer: Click the cog icon on the top-right side of the browser. Select F12 Developer Tools. Click the Network link (next to the ‘Profiler’ link).
- Refresh the webpage featuring an TinyMCE configured with the spelling service. Enter a misspelled word into the editor.
Locate the network results that match the following URLs:
If the network response for these services is 404, try the following:
- Take the service URL displayed as erroneous (example:
- Remove everything from the ‘1’ onwards (including the ‘1’) and replace it with /version. (example: Change
http://YOUR_SERVER:YOUT_PORT/ephox-spelling/version). The response code should be 200 and the body should display the version number.
- Take the service URL displayed as erroneous (example:
- If the response for the version URL is still 404, it means the service has not been started or installed correctly.
- To check the “Origin” value that the browser uses, open the network tools (Chrome in this screenshot) and refresh the page. Then enter a couple of words in the editor and select one of the requests on the bottom left (‘correction’ in the screen shot) and select the ‘Headers’ section. Look for the ‘Origin’ header value.
Note: The value of the Origin header sent by the must match the origin specified in the
application.confserver configuration. If it does not match, you must make the server configuration match the browser.
Sometimes the Origin header is never sent to the services, which results in the editor and services not working as intended. Refer to step 6 of Using browser tooling to investigate services issues and determine what the origin is - if you do not see an Origin header at all, please do the following:
- Try accessing the editor web page using your machine’s fully qualified domain name (FQDN) and keep the network tools open so you can see if the Origin header is sent back to the services. For example, if you have been testing on port 8080 on your local machine and the editor is instantiated on a page with path
tinymce/index.html, navigate to
- If you now see an Origin header being sent across, alter your
application.confand replace all instances of ‘localhost’ with the domain name of your machine.
- Restart the Tomcat / Jetty service.
- Reload the browser page and all should work well.
Even though you may have a large amount of RAM available, the Java Virtual Machine doesn’t get to see all of that - by default it is limited to only 256Mb.
For example, if you are using Tomcat, you can view how much memory is being consumed by apps. To do this you need to have the management console enabled.
On a vanilla install this is done by editing the file /tomcat/install/directory/conf/tomcat-users.xml adding these lines in:
<role rolename="manager-gui" /> <user username="tomcat" password="password" roles="manager-gui"/>
Then, restart the server and go to a browser and open the default tomcat page
http://localhost:8080. On the top right hand side are three buttons, the first of which should be “Server Status”. Click that link, login with the details you set above and you should be able to see the memory consumption (see the figure below for an example).
Edit the setenv.sh (Unix) or setenv.bat (Windows) to read as follows:
On Windows, please prefix each line with ‘set’ and remove the quotes . So the configuration would look like:
set CATALINA_OPTS= -Dephox.config.file=/config/file/location/application.conf set JAVA_OPTS= -Xms2048m -Xmx2048m -XX:PermSize=64m -XX:MaxPermSize=512m -Dfile.encoding=utf-8 -Djava.awt.headless=true -XX:+UseParallelGC -XX:MaxGCPauseMillis=100 CATALINA_OPTS=" -Dephox.config.file=/config/file/location/application.conf JAVA_OPTS=" -Xms2048m -Xmx2048m -XX:PermSize=64m -XX:MaxPermSize=512m -Dfile.encoding=utf-8 -Djava.awt.headless=true -XX:+UseParallelGC -XX:MaxGCPauseMillis=100"
Edit the start.ini file to read as follows:
#=========================================================== # Jetty start.jar arguments # Each line of this file is prepended to the command line # arguments # of a call to: # java -jar start.jar [arg...] #=========================================================== -Xms2048m -Xmx2048m -XX:PermSize=64m -XX:MaxPermSize=512m -Dephox.config.file=/config/file/location/application.conf
Restart the service and confirm the settings have been applied like so:
curl is installed by default on all macOS installations. Open the “terminal” application to use it.
Use your distribution package manager to install curl. See your distribution documentation for details.
Download and install the curl package based on your environment:
x86: http://curl.haxx.se/dlwiz/?type=bin&os=Win32&flav=-&ver=2000%2FXP and select either of the curl version: 7.39.0 - SSL enabled SSH enabled packages
- Unzip the package like so:
- Copy the path of the folder to where the ‘curl.exe’ is in:
- Open a cmd prompt. Start -> Programs -> Accessories -> cmd (or command prompt). Then change to that directory to the folder where the ‘curl.exe’ is found.Enter ‘cd’ (without quotes) and then paste in the path from step 2.
- Once in the folder enter ‘curl –version’ (without quotes) and ensure you get a valid version
If you are still experiencing problems, please contact Tiny Support.
