Site error

I'm unable to access or edit my website. Only one site seems to be affected. The tab reads "site error" and the page is blank after selecting edit site. Inspecting the Site Error page I found this alert("We've hit a snag converting some of your files. But don't worry -- your files are fine and can still be opened in SiteBuilder. For help converting your files, call " + SB.PartnerInstance.csrNumber..... When will this issue be resolved?
