Website compromised

[ Moderator note: moved to How-to and Troubleshooting. ]

Hi guys, it appears my website https://www.alittlelondoner.com has been hacked. My web host won’t reply to any of my emails so I can’t access my FTP. I have someone that may be able to help, but need to find out if any of my posts are backed up anywhere or if anyone can actually get my site back up and running? This has been going on for two weeks and I now have on top of the stress a loss of revenue. Thanks in advance, Triona
