if you are seeing a lot of 404 errors on your main dashboard, the issue is usually an outdated file path in your config. instead of manually updating everyy single page, you can use a simple script to find and replace the old string throughout your directory. always back up your files before running any automated changes.
if you skip the backup, you might break the entire site structure.find . -type f -name "*.php" -exec sed -i 's/old_path/new_path/g' {} +this method works for
nested folders too.
just clicking through every file is a waste of time.
