Hi, assembleagency, when you mention editing” a post / portfolio item”, are you referring to a custom post type?
If so, then there could be a permalinks issue with the post type.
Are you attempting to use custom slugs for that particular post type?
See https://developer.wordpress.org/plugins/post-types/registering-custom-post-types/#a-custom-slug-for-a-custom-post-type for what I mean about the custom slug.

Hi @assembleagency
I can only imagine how frustrating that problem could be! No worries, let’s see if we can find a solution together.
Can you temporarily enable debugging for your site, and then try creating a new post and try replicating the error? Here’s more on how you can enable debugging for your site: https://wordpress.org/support/article/debugging-in-wordpress/.
Once you have replicated the error, look for the debug.log file located in the /wp-content/ folder of your WP root (using your web host’s file manager OR using an FTP tool) too and see if it contains any specific error message. If it’s a rogue plugin (or your theme) causing an error, this will help us identify the same (if any).
If that doesn’t lead you anywhere – can you also check if switching the theme to a default theme along with deactivating all plugins (you can use Health Check plugin’s Troubleshooting mode for the same) fixes the issue?
In case you are out of luck with all these steps, can you navigate to the /wp-admin/ folder of your WordPress root, and see if the post-new.php file is intact, or if it is missing.
Please try out these steps and let us know how that went.
Thanks for the help above, post.new.php file is intact, enabled debugging and it returns these errors.
