wp-content renamed, now a problem

Per iThemes request, I changed the name of my wp-content folder. That broke all links to my images and attached documents, but I was able to relink them. However, my iThemes security log is now full of 404 error alerts.

I’ve search the forums and found a few different answers on this problem may be solved. Please let me know exactly what I should do to either revert the directory to its original name or correct the various 404 errors. I really do not care which solution I go with, as long as it corrects this problem. Thanks!
