I am not sure it fixes your problems as it did to me, but I just pulled 5.3.5 and it’s back for my sites. I guess there’s just been some formatting mixups like the “h3 .widget-title” which has been wrapped around the whole widget before…
Thanks to @hcabrera for the quick fix!
I’m running the premium version. The HTML slider om my site stopped working with the WP 4.0 upgrade as well. Hence I didn’t change any of the code, I wonder what I can do to resolve this.
Many thanks!
