I've been getting this error today when I tried working on my Wiki. I just installed MediaWiki about a week ago and have been edited every single day with no issues at all... until today.
"Darksiders Wiki uses cookies to log in users. You have cookies disabled. Please enable them and try again."
How do I assure that cookies are enabled? I did some basic research online, and I was told to edit the session.save_path... I don't have that. I have no idea where to find my php directory that has these files. I've looked everywhere and it's quite frustrating.
