I've posted this as a reply to a question, but though it was probably best if it was also a question in it's own right, so that it was more searchable/visible.
My post is below:
Ok, just running the 2.5 install again, and on step 2 after filling in the required DB fields I click on "Go ahead!" and get:
Arrrh! Can't install database.
Invalid bind-variable name ':title'
And if then I click on "Go ahead!" again I get:
Arrrh! Can't install database.
Mysqli statement execute error : Duplicate entry 'currentTheme' for key 'PRIMARY'
And that's as far as the install gets.
I have another DB that lets 2.0.4 install with no problems at all.
Any ideas please? Thanks
