Solved Issue with editing footer

For our footer, we are just using the normal Divi Library items. Thus, this issue is related to Divi theme itself. Might be conflicting with some other plugins.

First thing to try is to clear your browser cache & site cache & see if it works.

Also try to edit others Divi Library items & see if it works.

You may also try to enable Safe Mode & see if it works: WP Admin > Divi > Support Center > Safe Mode > Enabled

Let me know how it goes.
