How to make a link to the page in the subfolder php?

Faced with the problem. If the page page.php is at the root of the site, all connected without problems. But my page is this path: htdocs/event/2303/page.php . Already feels like shit but still gives: HTTP ERROR 500
Many thanks in advance for the help!
