what is your URL please ?

maybe test your connection / create testbdd.php and past it /
<?php
$link = mysql_connect(‘localhost’, ‘root’, ‘password’);
if (!$link) {
die(‘Could not connect: ‘ . mysql_error());
}
echo ‘Connected successfully’;
mysql_close($link);
?>

check your permalinks structure maybe

error message please ?

sorry, i dont know.
Good luck.

and
with your phpmyadmin

UPDATE wp_options
SET option_value = replace(option_value, ‘https://www.oldurl.com&#8217;, ‘https://www.newurl.com&#8217;)
WHERE option_name = ‘home’
OR option_name = ‘siteurl’;

add this in your function.php
update_option(‘siteurl’, ‘https://yourwebsite.com/&#8217; );
update_option(‘home’, ‘https://yourwebsite.com/&#8217; );
