WordPress WordPress Hooks - Actions and Filters An Overview of Hooks in WordPress Working with $wp_filter

WP-Hooks Theme Not working after update

I recently updated the WordPress install for my local development copy of the WP-Hooks website for this course. Since then, whenever I go into the admin panel, the panel is blank. There are no menu items, just a black strip down the left side.

If I use the Customize option, when that window opens I see a page of repetition of the same error message: Warning: var_export does not handle circular references in C:\Users\Wil\Documents\Websites\www.wphooks.dev\wp-content\themes\wp-hooks\examples\export_wp_filter.php on line 2. This is repeated for each output.

Other than the WordPress update, nothing has changed. I am certain it is a problem with the sample theme, because when I switch to a different theme in the Customize window everything works as it should. I understand this is not a full theme, but I cannot continue with the course if I cannot use the admin panel. I am eager for any insights.

Whats the error log say? Do you have wp-debug on?

Sue,

Debug is on but not throwing an error; and there is nothing in the console log. The issue seems to be with Customize and WP-Admin.

UPDATE: When I changed the functions.php file to require example/wp_title.php instead of list_hooks.php the WordPress functionality comes back. So, it seems I can either list the hooks or see the admin tools.
