Divi Under Construction plugin for Divi
The D.U.C. plugin for Divi Theme allows you to build your under construction/coming soon/ under maintenance pages using the Divi builder.
“Build your Under Construction page with Divi — or use one of the 2 we’ve included.
Enable the Under Construction module and select your page from step one.
If desired, enter the IP addresses of users that shouldn’t be redirected. Only anonymous users will be redirected by default.”
