Hmmm, hope this helps… I fount it in the error logs

[05-Dec-2018 16:51:50 UTC] PHP Fatal error: Uncaught Error: Call to a member function authenticate() on null in …/wp-content/plugins/yith-woocommerce-social-login/includes/class-yith-social-login.php:189

I had the same problem and my WP version is 4.6.1 and I do not have Types plugin installed. Seems that other plugin was the culprit, The Events Calendar…

My eyes hurt! For me, the entire admin panel is in BOLD text… what happened to WordPress???

I’m running Chrome & Firefox on Linux Mint 17, and I have the same problem on both browsers. Seems that “Roboto” is the font used in my case…

I have the same problem but I could identify that WooCommerce plugin is causing it to malfunction. I tried to disable plugins one by one until I was able to save again.

Anyway I have a theme that supports WooCommerce customization and I can’t do anything because it doesn’t work with the plugin activated. When it’s disabled, it works but I do not see the WooCommerce section in the Customizer…

QUESTION: Where is Customizer saving the data? It is possible to alter the file or database table and add what I need???

Same here… the plugin doesn’t work with Avada or Enfold themes… I believe it doesn’t work with many other themes from ThemeForest…
