Yesterday a colleague updated WordPress and a number of plugins on our site.
Since then, the visual editor displays the contents of pages and posts as HTML, it is also white, whereby we first thought that it wasn't displaying the contents as well.
I have been able to switch to HTML-mode which displays as expected, but when I switched back, the Visual/HTML tabs stopped working.
Going through a few troubleshooting ideas offerd on a number of fora, like re-uploading the wp-admin and wp-includes folders, deactivating plugins one by one to single out the culprit... all to no avail.
The fact that the text is white is annoying, but on top of that, most of my colleagues have no idea what HTML is. Any help would be greatly appreciated.
