Two, presumably unrelated, problems in my installation with a shared hosting outfit.
1. The install process tells me that mod_rewrite is not enabled; I believe it is enabled, so I forced installation to proceed.
2. Now, the CMS login refuses to recognise the email address I gave during installation.
I have repeated the installation process, and got to the same result, so I am confident that this is a real problem and not the result of a keystroke error.
So: not what you would call a smooth install. Do I give up, or can anyone suggest a solution?
