Lightweight script

[Ishod]

Good day. I have a question for the experts. I have been building WordPress sites for a long time. However, now I need to switch to a different script. The reason is this: I am opening a forum site and I want to provide subdomains to users. But my hosting company has imposed a limit on the "number of files" for my unlimited package. Since there are over 1000 files in a WordPress script, I need a lighter script. My total file limit is 250,000. If I use 1000 files for a site, the host will not be happy. I am looking for an easy-to-use simple script. Thank you.
