Hi.
Are trying to edit and add code under Appeareance->Customize->Additional CSS. It will somethimes stay, but most of the time it dissapears or the code we have deleted is back again. Ref the last case I opened, the code for the width of the blog is coming back.
Have now deactivated Autoptimize. No change, still not able to remove the code. Remove the code, press publish, the blogpost refreshes, and nothing happens.
Are you using Dashlane or another password plugin – I’ve had issues with this conflicting with the customiser preview mode in the past – maybe try the Simple CSS plugin from Tom for your additional CSS and see if you have the same problem?
Using Edge, with no Dashlane or any other plugins installed. Still cant remove code in Additional CSS. Using Simple CSS is working, but dont know how to remove the code for the width of the blogpost.
