I have tried 3 times to do a scan but it never finishes. On the 1st scan it scanned for about 4 hours and never finished. 2nd scan I left running for about 12 hours and never finished. I am on the 3rd scan and it also never ends. It gets to ” Sending request to Wordfence servers to do main scan” in about 3 minutes and from there it stays hours and hours but never ends. Please advise..
