Delete check.php after confirming setup works.
mod_rewrite test
If mod_rewrite is working, this link should load the home page (not a 404):
/ — /setup — /browse
Direct PHP access (no rewrite needed)
These always work regardless of mod_rewrite:
/index.php — /index.php?_r=setup
Next step
Share the output of this page if the 404 persists and mod_rewrite status is shown.
