So the customizer also broke for me and I wanted to post what fixed it in case anyone has a similar situation. I was using Generatepress and Webcomic together on a Flywheel Local install to test out how to use them togeter for a client. Sometime while I was testing out different layouts I noticed my Customizer wasn’t working anymore. I’d load up the page and all I’d see is the name of the site and no options.
I tried everything:
– Turned off themes, plugins. Even deleted webcomic and reinstalled.
– Swapped themes (weird exception the old Comicpress theme I was converting)
– Deleted cache, adjusted my php version/memory limit
– Turning on WP_DEBUG did not post any error on screen or generate a log
Nothing worked. But what did fix it was using this tool WordPress linked to in their guide on tracking errors.
In particular, it was this line of code in my wp-config file:
@ini_set(‘display_errors’, 0);
Weirdly, I can now see my customizer again. I did turn on the debug bar and took screenshots of everything I saw in case this helps someone. I’ll link to it here in a zip file.
Anyways, I hope this post helps someone in the future!
