An uncaught Exception was encountered

Type:Exception

Message: Session: Configured save path '/usr/share/nginx/html/terminal_php/application/../sesssion_files' is not writable by the PHP process.

Filename: /usr/share/nginx/html/terminal_php/system/libraries/Session/drivers/Session_files_driver.php

A PHP Error was encountered

Severity: Warning

Message: fopen(1f194f2bef7c1013a926c931c860a0eb62071b84): failed to open stream: Permission denied

Filename: drivers/Session_files_driver.php

Reason: The permissions to access the Session_files_driver.php file are not enough, because the session_files folder is the file that stores the session. However, every time the user accesses, the writing, reading and execution of the dynamically generated session will be performed. Therefore, , just set the "read, write, execute" permissions.
Solution: Increase permissions (chmod 777)

Solution: Increase the server Account permissions (chmod) ​ ​ ​
