One of my wordpress installations is not working, apache error log reports this message:
ModSecurity: collection_store: Failed to lock proc mutex: Permission denied [hostname "xxxxx.com"] [uri "/php73-bin/php-cgi/wp-login.php"] [unique_id "xxxxx"], referer: https://xxxxx.com/wp-login.php
The mentioned uri /php73-bin... is not part of the wordpress installation so I suppose that maybe is something related to the frontend proxy?
Please could you help me troubleshooting the error?
Thank you very much.
