 * Hi, i just got this on one of my sites. There are two other sites on the same
   server that do not have the problem. It worked fine 2 days ago and no other plugins
   have been updated since. It just seems to have thrown an error all on its own!(
   I have taken the directory out of the error messages for security purposes)

 * There is an ongoing issue affecting servers with Imunify 360. The file “wp-content/
   plugins/all-in-one-wp-migration/functions.php” is being falsely flagged and deleted
   due to a detection error. We have reached out to Imunify for a resolution.
 * Temporary fix that works:
    Go to your Imunify360 tab and add an entry to the 
   ignore list, E.G.: /home/myawesomewebsite.com/wp-content/plugins/all-in-one-wp-
   migration/
 * Another way you can do this is to navigate to your website root folder and create
   a file called: ‘imunify360.ignore’
 * Edit ‘imunify360.ignore’ and add the following:
    wp-content/plugins/all-in-one-
   wp-migration/
 * Don’t forget the last slash!

 * What if this has no effect? I just set this up as per the instructions and it
   didn’t do anything, I still get the error.

 * torndownunits you need to contact the software vendor. I am unfamiliar with imunify360
   and cannot advise on the exact process. The community has provided the instructions
   above.
