I bought a new computer recently and I’m moving my files from one localhost to another. When I brought over a website I’ve had no issue with to date, I couldn’t login. I was getting a $_SESSION Variable not set error. So I cleared the cache folder to see if that would help but unfortunately it made it worse. When I cleared the cache I couldn’t see the site at all and was getting an Error 503: Site Temporarily Unavailable. I checked all my config.core.php files and they are correct.
Anyone come across this before?
