After the update to WordPress 4.9.6, I got a very strange issue that I am not able to write anything in the WordPress editor in visual mode.
I am getting this span code instead of text when I am trying to switch from text to view.
<span style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" data-mce-type="bookmark" class="mce_SELRES_start"></span>
Can anyone help me on this issue? I can’t write anything.
