You edited a page through the Text editor, but when you switch to Visual editor, some of the HTML you added changes or is removed.
This is known to happen specifically when adding Bootstrap Collapsible Accordion Menus and anchors but may happen with other bits of code as well.
If you add a collapsible accordion menu to your page through the text editor, it deletes the following line of code from every panel:
<a class="collapsed" href="#PanelID" data-toggle="collapse" data-parent="#accordion">
It also deletes the corresponding
</a>. Note that this
<a> tag wraps each
Sometimes when you add an anchor on a page, it will later disappear. This does not happen all the time but it appears to happen by either adding an anchor in the Visual editor, switching to text editor, and switching back to Visual, or adding an anchor in the text editor and switching to Visual.
Steps to Fix the Issue
Because there is no known solution for this issue, the best thing to do would be to avoid going back into Visual editor on any page that has a collapsible accordion menu/anchor. If you do go into Visual editor, you could do one of two things:
- Click Browse next to Revisions in the Publish box and restore the latest version that had the full code (if there are any).
- Go back and manually re-add the code yourself.
