I am managing a Wordpress multisite setup with the following websites:
The main portal: which connects to
The issue arises on all pages of gprgebouw.nl and gpradvies.nl but not on the other domains. Attached is a screenshot of the homepage of gprgebouw.nl
The problem scenario:
- the right sidebar moves under the content area
- the bar-graph icon image increases in size
- grey borders of the sidebar extend to the top of the content area
In particular, point 3 leads me to believe that somehow the content area is not properly closed, though I cannot trace this in the HTML source.
The strangest part is that only these specific websites are affected and not others, even though they share the same Javascript and plugins and most CSS (except for some color variations).
Everything displays correctly in browsers like Firefox.
Any suggestions on what might be causing this issue? I currently use selectivzr and modernizr for IE up to version 8.
