I cannot change in wp-admin between visual and html editor.
The error only occurs with custom types, not with pages and posts.
The following javascript error appears in the console:
Uncaught TypeError: $headers.imagesLoaded is not a function in
/wp-content/plugins/types/vendor/toolset/toolset-common/toolset-forms/js/file-wp35.js?ver=0.1.2
The site is updated to the latest version of wordpress and types.
I have tried to disable all plugins but the problem persists.
Since you've already tried disabled the non-toolset plugins there is no need to do this again. What I would like for you to do for me is to provide me with a copy of your site if possible.
This way I can investigate the issue further and also to ensure that it is also not a server issue.
