I ran the file scan using Defender and it identified that index.php in the root had been modified. I used the fix function to restore to the original but it left the index.php blank. I downloaded and copied the original into index.php and it still identifies it as being modified and when I use the restore function it still blanks it. Not sure if something is awry in the Defender plugin but thought I would report it. For the moment I have told Defender to ignore the issue. Thoughts on how to proceed?
