If you try to import a large amount of data at once in WordPress, you may experience a timeout. This is because the import process exceeds the time allowed by the server.
To solve this problem, it is useful to split the entire data and import it separately. For example, importing posts and media separately.
However, it is important to note that importing posts alone will not import eye-catching images. To include eye-catching images in the import, you can use a plugin such as “Attachment Importer”.
