I moved wordpress forom iszablony.pl/wordpress to iszablony.pl using this method:
1) change site url in settings
2) copie index.php and .htaccess to main folder
3) move wp-config.php
4) edit require('./wp-blog-header.php'); to require('./wordpress/wp-blog-header.php');
5) update direct links in settings

Everything was fine, to time when i tried to log out.
Insted of logout and redirect i get this adress:
http://www.iszablony.pl/%E2%80%9Dhttp:/www.iszablony.pl/wordpress/wp-login.php?action=logout&redirect_to=http%3A%2F%2Fwww.iszablony.pl%2Fmoje-konto%2F&_wpnonce=128c43656c%E2%80%9D

in browser %E2%80%9D is " so the adress looks like that:
http://www.iszablony.pl/"http:/www.iszablony.pl/wordpress/wp-login.php?action=logout&redirect_to=http%3A%2F%2Fwww.iszablony.pl%2Fmoje-konto%2F&_wpnonce=128c43656c"

what should i do now ? how to fix this ? please help.

Hi Dawid,

Ensure you have updated the sites URL. This needs to be changed in wp-config and also the wordpress installation in Settings.

I usually make these changes in MySQL.

If you would like a more in depth guide on how to change your site URL you can visit https://codex.wordpress.org/Changing_The_Site_URL

Kindest regards,

Samuel Rose.

but my wordpress core files are constantly in iszablony.pl/wordpress
So when i change site URL than my wordpress wont work, am i right ?

Hi Dawid,

The Site Address is what people go to to access your site.

The Wordpress Address is where your WordPress core files are.

Please do not confuse these.

Kindest regards,

OK in DB in wp_options there is field siteurl - and it is wordpress files adress
and there is field home - which is what people go to to access my site.

if i\'m wrong, please, correct me

You want to only change the site address as this is what people go to to access your site.

If you can get into the backed of your wordpress go to Settings > General.

Edit as shown below:

WordPress Address (URL): http://www.iszablony.pl/wordpress

Site Address (URL): http://iszablony.pl

Kindest regards,

Samuel Rose.
