Width Set to 146 Inline

I fixed this with this CSS in child theme (it’s responsive):
.fb-comments.fb_iframe_widget span {
width: 100% !important;
}

You have to increase specificity to override default class.

I’m having the same issue. The widht of the comments area isn’t 100%, but 146px. It’s been this way since last update. Please fix your plugin. Many thanks in advance!

Thanks nupy, I didn’t identify the class correctly in my attempt.

This code worked for me, for some reason 100% was causing the iframe to disappear completely.

.fb-comments.fb_iframe_widget span {
width: 500px !important;
  display:block;
}
