Answering your first question, yes it is absolutely possible to have one installation of WordPress running ‘within’ another (i.e. installed at example.com and example.com/child). I have something like that running right now.
It is not possible to override header/footer via hooks in respective get_header()/get_header() functions. However it is often overlooked that these function allow input and loading different headers.

There are two ways to fix this: Manually re-write URLs The … Read more
It might be best not to think of it as “folders” since it all runs off of index.php. The rest of the URL structure does not represent the file structure (eg Folders) but the permalink rewriting structure. (And thus make sure you have Permalinks enabled.) To create example.com/miami, you would create a Page within WordPress … Read more

You cannot use bloginfo() while your are outputting using echo because bloginfo it self also out puts string using echo. Below will work for you, you also have extra double quote which i have removed…. <?php $attch_id_1 = pn_get_attachment_id_from_url(get_post_meta($post->ID, ‘img1’, true)); $image_attributes_1 = wp_get_attachment_image_src( $attch_id_1, ‘full’); $attch_id_2 = pn_get_attachment_id_from_url(get_post_meta($post->ID, ‘img2’, true)); $image_attributes_2 = wp_get_attachment_image_src( $attch_id_2, … Read more

Checking for page templates in child theme
Typically, each instance of WordPress has it’s own database. If you have 20+ seperate WordPress installs, then you should have 20+ different databases. Each database is going to have quite a few tables. If it is asking you to clear the database tables, then it is most likely only referring to the data for a … Read more
