Various PHP warnings displayed when creating threads/posts

[Goon3r]

Hello,

Apologies if this has already been reported i did search but couldn’t didn’t anything.

After creating a new thread or saving a post then various PHP warnings are displayed on screen.

Array access issues on the ‘post_author’ key and various header modification errors usually caused by headers being mutated after output has been sent.

Attached a screenshot showing the exact warnings.

Nothing seems to he functionally broken, but something to be aware of nontheless and it also might be worth turning off error reporting in production to alleviate potential security concerns
