@Dillon-Brown What should we do this here? Delete all these language strings?
@ChangezKhan If they are truly unused then yes, a simple search won't always work as some strings are built dynamically.
@Dillon-Brown if some language strings are built dynamically, then how can we check whether the string is unused or not? Is there any way to do that?
Small addition: these labels have been removed earlier, in versions 7.9.x,
but again appeared in version 7.10.8
Was it done on purpose or by mistake?
@ChangezKhan There's no easy way to check but you can play around with grep and do some manual testing to confirm, see #4291 for an example.
@likhobory Looks like a mistake, they were removed in the hotfix branch but then re-added in when hotfix-7.8.x was merged back into hotfix.
@likhobory sorry, this is off-topic here, but can you reproduce the bug described in this thread?
