Before the latest Ver. on OCT, there is no issue for PRO.
Now, there is a big one.
With nice two plugins as follows, which are for performance and securities.
Autoptimize|https://wordpress.org/plugins/autoptimize/
Clearfy|https://wordpress.org/plugins/clearfy/
With “Clearfy” and “Autoptimize” setting ON for java script to minimize simply, the PRO stop loading for editing.
When “Clearfy” off from WordPress and “Autoptimize” setting for java script to minimize simply ON, the Pro works properly.
This means some java scripts in Clearfy are the reason for affect to some PRO functions.
So far I have found only in Editing issue means only in the admin area, I use both plugins with setting java is ON.
And only when EDITING, to switch setting is OFF for java script in Autoptimize which is a bit annoying way to run the site.
Please kindly check if there is hopefully a good solution for this issue.
THANKS IN ADVANCE.
