Hi guys, I was trying to translate some phrases to Vietnamese and kept getting this problem. It showed that there is an error on permission to access admin.php. I have only got this problem since yesterday. As far as I remember, I didn't do or edit anything before that. The problem is not that bad as I am still able to translate the phrase after closing the error box. But sometimes it keeps showing up again when I try to translate other phrases. I can't find much thing from the server error log and the file health check is ok too. Hope somebody can tell me the cause and the way to get rid of it. Thanks!
