Install.php returns me to homepage?

If you put WordPress in the blog sub-folder, meaning wp-config.php (and wp-admin etc) is in the blog sub-folder, then you would navigate to https://www.giggleboxphotography.com/blog/wp-admin/install.php

I would also reupload your WordPress files as it looks like you didn’t get a clean upload.

Installing WordPress
Uploading WordPress to a remote host

Yeah, sorry, that’s what I meant. That’s the link I’m using.

What do you mean that I didn’t get a clean upload? All the files are there, what should I do? My internet is really slow and it took 8 hours to upload it the first time.

if you look at the errors – they reference files that are not there from your /wp-includes folder.

Use a good FTP client and it won’t take near so long to upload files.

It’s not my FTP client, I use Dreamweaver. My awesome free internet at my apt connects at between .5 and 1 mbps, if I’m lucky.

Thanks, I guess I missed that folder!
