This checker looks like my problem:
I cleared the browser’s cache with no luck.
So far, I haven’t found where the wp cache is, and searching the forums for “clear cache” hasn’t helped….
any advice??
is_blog_installed() X-Ref
Test whether blog is already installed.
The cache will be checked first. If you have a cache plugin, which saves the
cache values, then this will work. If you use the default WordPress cache,
and the database goes away, then you might have problems.
Checks for the option siteurl for whether WordPress is installed.
return: bool Whether blog is already installed.
