@GumbyDmmit renaming the plugins folder makes no difference for me 🙁
I’m still struggling with this.
Now it appears that the “Page Attributes” section on the single page edit like: /wp-admin/post.php?post=4&action=edit never finishes loading either.
@sonic1243 the post.php is located in /wp-admin/includes/post.php would be interesting to know if that helps in your case as well.
Stupid mistake, I commented this out by mistake in wp-includes/widgets.php line 323:
function register($widget_class) {
// $this->widgets[$widget_class] = & new $widget_class();
}
@richardwpg: Thanks for the suggestion. No, I am in “Site Admin” In ‘Network Admin’ dashboard there is no Menu “Appearance” > “Widgets”.
