Deactivation of HTML / Javascript / iframe content in ILIAS 8

Why are HTML / Javascript and iframe content no longer supported on ILIAS 8?

In the opinion of the ILIAS developers, the security risks resulting from the user-side embedding of such content cannot be reasonably limited. Therefore, the decision was made to no longer allow HTML/Javascript and iframe content from ILIAS 8 onwards. In future, this content will no longer be evaluated or executed, but displayed as text.
This function was mainly used to integrate external pages via "iframe" (e.g. YouTube videos via "embedding code") or to design content on ILIAS page editor pages beyond the existing possibilities of the page editor (e.g. via HTML tags such as "<strong> .... </strong>").

What content and objects are affected?

  • Course and group pages ...
  • Learning module and content pages ...
  • Glossary entries ...
  • Page design around ILIAS test questions ...
  • Portfolio pages and page templates ...
... that contain iframes / HTML or Javascript content.

What content is not affected?

  • Formatting made via the page editor functions or via adjustments to the content style of a page or learning module.
  • YouTube videos that have been integrated using the "Insert Image/Media" function in the page editor via a link to the YouTube video will continue to be displayed as embedded videos.
  • Videos embedded using the "Insert Video from ViMP" or "Insert External Video" (from Panopto) functions will continue to be displayed without errors.
  • LaTeX content embedded via MathJax or double "$" is still displayed correctly

How can HTML / Javascript and iframe content be converted?

Solutions for videos

1. Embedding YouTube videos: 
  • Open the video in your browser on YouTube
  • Copy the URL from the browser address bar
  • Open "Customize page" on the relevant ILIAS page
  • Click on the "+" sign where you want to insert the video and select "Insert Image/Media" and then "From URL" on the left
  • Copy the URL of the YouTube video into the "URL" field and click "Insert"
2. Integration of Panopto videos:
  • Open "Customize page" on the relevant ILIAS page
  • Click on the "+" sign where you want to insert the video and select "Insert External Video"
  • You can now select and insert the appropriate video from your Panopto videos
3. integration of ViMP videos:
  • Open "Customize page" on the relevant ILIAS page
  • Click on the "+" sign where you want to insert the video and select "Insert Video from ViMP"
  • You can now select and insert the appropriate video from your ViMP videos

Solutions for text formatting

When formatting texts on ILIAS, only use the formatting offered via the editor.
Alternative for advanced ILIAS users:
You have the option of creating your own styles if the existing formatting is not sufficient for you:
  • Go to "Customize page" and click on the blue action arrow to the right of the "Finish Editing" button
  • Select "Style". There you can select an alternative style under "Current style". Or you can create your own style by clicking on "Create Individual stylesheet"
  • You now have the option of modifying the existing style. To do this, enter a name for your style and save it. In the next step, you can adjust all fonts, boxes etc. accordingly.

How does it work?

Further information and instructions for embedding videos (ViMP, Panopto, Mediacast, Interactive video) can be found on the Embedding videos info page.
