I had my wp instalation running well and happy on my localhost.
Recently I moved it to my server, and now the loading animation of the theme doesn’t show up.
I found it is an issue with the plugin Types by Toolset. Removing the plugin brought the animation back.
Any ideas why is happening and how to fix it?
Try to update Types plugin to latest version and try again. I just tried with WP 4.3, and all plugins, and theme updated to latest versions, and it is working. If Types plugin displayes register toolset message, delete it, and install latest version afterwards.
