Hello – This post is meant to be informative to the developers concerning a failed revert.

After running a scan, malware was found in all the theme functions.php files.

I clicked on ‘clean’.  The automatic site test stayed red, indicated the clean did not work.  I clicked on ‘revert’, but the site remained broken.

The malware was on line 1 of the functions.php file. The error after cleaning was:

Parse error: syntax error, unexpected ‘)’ in /home/content/p/r/o/prongpower/html/wp-content/themes/twentyfifteen/functions.php on line 1

Malware was still in the file, with a leading ‘)’ causing the error.

I resolved by restoring a clean file from backup.

malware infected file available by request if it helps your troubleshooting.
