error when activating

this is the error message I get when trying to activate. i think it’s a plugin conflict:
Parse error: syntax error, unexpected $end in /data0/htdocs/websiteurl.com/wp-content/plugins/wp-autosave/wp-autosave.php on line 112 Warning: Unknown: open(/var/lib/php/session/sess_s1bfq15ao3qve2reltj74neb84, O_RDWR) failed: Permission denied (13) in Unknown on line 0 Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0

Is there any help I can get on this?

Thanks so much!
