Problem
The display of the course page layout appears broken (i.e. topics displaying behind each other so they are not visible, blocks appearing under topics even though there is space on the right sidebar and the window is larger than a mobile or table display)
Solution
Broken page layouts are almost always caused by content with malformed formatting/HTML being pasted into the editor. To prevent (and resolve) this issue, it is best to always paste content in as plain text and do any formatting (i.e. headings, bold/italic, lists, tables) with the AsULearn editor.
To paste content as plain text, use the keyboard combination CTRL (CMMD for Mac) + SHIFT + V (instead of the standard CTRL (CMMD for Mac) + V).
