URGENT – My site was shut down by the host !!!

I hosted my site on SiteGround, and I am about 6 months there. Last week, I performed the update of my theme (arcane) for the newer version. I noticed the site got a little slower. Now, I received an email from the host, saying that they were disabling my site because I was using too many resources. They submitted a report that shows a problem in the site database. Follow:
