I downloaded Esplanade theme from the worpress site, installed it, activated it, and the site crashed in that on only page the comes up is a page with a “0” on it. This happened after 203 reinstalls of the whole wordpress installation. I saw the forum suggestions on previewing first, then activating. Renaming the default theme directory, etc. Nothing worked. Interesting that on another wordpress site, same web host, the new theme installed fine. It is not just esplanade, I can’t switch to any other theme (so far) on this particular site.
