Please go to wp-content/plugins folder (use a ftp account) and rename Kirki plugin folder. This will deactivate current plugin and enable site again. Then in wordpress dashboard, install Kirki plugin from the message in dashboard. Update it first, if there is a message requiring it’s update.
if you still have issues, send us some wp and ftp credentials in a private reply. So we can check it.
Please keep in mind that after theme update, some plugins will be automatically deactivated. Just check to have all required plugins installed and active first.
