I have a website with the main page written in HTML and CSS. The forum page is written in React.js and node.js and the blog is written in PHP and MySQL. I am unable to integrate all the additional pages to main site due to different languages, backend, logic and theme used in the forum and blog sites.
Will creating sub directories for forum and blog and then linking them to main site through URL solve my problem?
If yes, then how can I create a sub directory.
Any help would be appreciated.
Thank you
