Initially, everything worked fine when we used PHP 7 for our WordPress setup. File uploads were smooth, and there were no issues. However, after migrating to PHP 8, we suddenly encountered the Nginx 500 error whenever attempting to upload any files to the media.
After exhausting common solutions like checking file permissions and increasing client_max_body_size, I discovered the real problem: migrating to PHP 8 required additional Nginx adjustments, specifically balancing both client_max_body_size and client_body_buffer_size.
I updated my Nginx configuration with:
client_max_body_size 100M;
client_body_buffer_size 100M;
Once these changes were applied, file uploads worked seamlessly again. The key takeaway is that transitioning to PHP 8 may require tweaking Nginx settings, especially balancing these two parameters to resolve file upload issues effectively.
