Wordpress not reflecting changed of the database - php

Question

my problems started when I moved my website to another folder (from /dev/ to /).
I have gone through the whole database in order to change all the hardcoded /dev/ into / but I still notice that wordpress, somehow, still uses the old values.
Basically the website uses information that are not there anymore.
I checked my own and the server cache and they all seem to be clean (the server doesn't even seem to have that feature on).
So, I am pretty much lost...

Answer 1

When you move a wordpress install, you need to change the site URL throughout your database. To do this you'll need to export your current database via PHP MyAdmin, and then use a tool like:
http://interconnectit.com/products/search-and-replace-for-wordpress-databases/
...to do a search and replace on the entire database.
Search for:
www.yourwebsite.com/dev
replace with:
www.yourwebsite.com
Then import the new database, open your Wordpress site via wp-admin and re-save permalinks.

Run this query in your database
set #oldurl = 'http://oldwp-url.com', #newurl = 'http://newwp-url.com';
UPDATE wp_options SET option_value = replace(option_value, #oldurl, #newurl) WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE wp_posts SET guid = REPLACE (guid, #oldurl, #newurl);
UPDATE wp_posts SET post_content = REPLACE (post_content, #oldurl, #newurl);
UPDATE wp_posts SET post_content = REPLACE (post_content, CONCAT('src="', #oldurl), CONCAT('src="', #newurl));
UPDATE wp_posts SET guid = REPLACE (guid, #oldurl, #newurl) WHERE post_type = 'attachment';
UPDATE wp_postmeta SET meta_value = REPLACE (meta_value, #oldurl, #newurl);
