Can't access wordpress site, by logging in or just viewing

O, and when I use the bookmarked link to the dashboard it gets redirected to:
https://www.beesknees.nl/colettevanessen/wp-login.php?redirect_to=http%3A%2F%2Fwww.beesknees.nl%2Fcolettevanessen%2Fwp-admin%2F&reauth=1
if that is any clue to how I can fix it again.

I’m close to having to install WP all over again and starting from scratch.
Please help!
kind regards to whoever can help me fix this,
Colette

Hi audreycolette,
I am not certain what is going to work best, but if you have access to your site’s control panel and / or FTP, you should be able to rename your sub-folder easily. Then, try going to the new URL. If renaming still does not resolve the issue, you may want to delete your current install and re-install WordPress. Just make sure your site URL matches your Login URL + /wp-admin/ or wp-login.php. Hope this helps!

Hi Jason,
When I go to the new URL (which was once the old one) nothing loads.
https://www.beesknees.nl/colettevanessen) Even though I can see the files are there in my ftp program.
My site URL matches my login URL but nothing happens.
By now I’ve:
– Replaced the wp-admin and wp-includes folders from a fresh download of WP
– Tried https://www.beesknees.nl/colettevanessen/wp-admin/install.php -> nothing. Everything in the URL after beesknees.nl is gray / ghosted.
– Tried filling the database details in the wp-config-sample.php file and then saving it as wp-config.php and then going to https://www.beesknees.nl/colettevanessen/wp-admin/install.php -> still no dice.
Is there a way to reinstall WordPress without loosing the content I already put in?
regards,
Colette
