How to debug a plugin that whitescreens

Remember: _activate() should be reversible, _install() owns permanent structures.

Hooks are the heart of MyBB plugins —

Code: PHP

$plugins->add_hook('pre_output_page', 'my_func');

is where everything starts.

Returning true from a by-value hook replaces the argument; by-reference hooks mutate in place — check the call site.

Any tips, experiences or strong opinions welcome.
