Clicking on this option in the footer opens the current page in 'plain text' mode. All HTML tags of the page are removed and the outout of the page will be in plain text (no design and no scripts).

This can also be called by passing an URL/Get - parameter 'notags=1'.

For example:

https://certus.in/site/?notags=1

Or:

https://certus.in/site/pages/cia-en/news-en.cia?p=10&notags=1
