Sorry guys. The WYSWIG (?) or rich editor is not loading/working.
After the page was loaded, you can’t encode/type (for new post) or edit (for existing post), unless you transferred to the text tab.
I’m having the same issue. I followed your instruction, Matthew, and identified the plugin that causes this. It’s jetpack.
I’m at the 2015 theme and activating the plug-ins one by one, thus, have identified this as the cause.
Hope this will be addressed soon. Thanks
