Fatal error/exception

This site is under development.

I’m getting this error:

fatal error/exception:
File: /wp-content/plugins/simple-classifieds/assets/templates/avatar.php
Line: 10
Request Id: 4b26cd8d9e
Plugin: simple-classifieds

The server administrator said this:

This was caused by appending an extra character “i”. php 8.4 crashes directly in such cases.
