I am following the wordpress upgrade procedure here: https://docs.civicrm.org/sysadmin/en/latest/upgrade/wordpress/
the instrucutions say to clear cached files by removing all files in the templates_c directory.
I have a subdirectory en_US within the templates_c directory which has many further subdirectories. Am i supposed to delete these too? or just the files in the template_c director itself?
many thanks
