Reply To: Date format and language
SWA has a date in english, you change to spanish and now SWA is in spanish and previous activities are in english. It’s just normal !
Now you have verified and nothing changed. Have you create a new content meanwhile ? Deactivating and reactivating plugins has no influence on the SWA. If you don’t use specifically this plugin, so far he provides some activity (like add a picture to the album) who goes to the SWA, who don’t see absolutely nothing.
Could be that if you apply changes about date format in WP settings, or in a plugin, this will not appear in the site wide activity. The modification will only apply after you did the change. SWA has no backward compatibility with settings. Also for language format.
Sorry for this detail, but it must be knowed before complete headache
