Solution 1:
One common reason WordPress URLs still point to the old site is because they are stored in the database. Running the following SQL queries in phpMyAdmin can help fix this:
UPDATE wp_options SET option_value = REPLACE(option_value,'old_site','new_site');
UPDATE wp_posts SET post_content = REPLACE(post_content,'old_site','new_site');
UPDATE wp_posts SET guid = REPLACE(guid,'old_site','new_site');
UPDATE wp_postmeta SET meta_value = REPLACE(meta_value,'old_site','new_site');
Another possibility is that your hosting account includes a folder path with your username. For example, in the wp_options table you might see an upload_path like:
/home/[folder_old_id]/public_html/wp-content/uploads
To fix this, update the path using a query like:
UPDATE wp_options SET option_value = REPLACE(option_value,'folder_old_id','folder_new_id');
👉 Always back up your database before running these queries.
