WHMCS session problem

How to fix this ? I used PhP 7.3 this folder /var/lib/lsphp/session 777 but error not fixed

PHP Session Support
PHP session support is enabled.

Session autostart is disabled.

The PHP session save path /var/lib/lsphp/session is not writable. Please investigate the session.save_path PHP setting or contact your system administrator

Did you make it recursive (so the PHP version folder would also be writable as mine mentioned the version folder also)? I have the same issue and was just starting to fiddle with it.

gave the session path to tmp and try

How? I tried but it won’t work.
