Possible Causes:
-Missing or incorrect .htaccess rule
LiteSpeed is Apache-compatible – a misconfigured .htaccess file can block certain paths.
-ModSecurity or WAF rule
A Web Application Firewall may detect access to /admin.php?options/update as suspicious and block it.
-File permission issues
If the file isn't readable or has incorrect permissions (chmod, chown), the server will deny access.
-Hosting panel configuration (e.g., cPanel, CyberPanel, aaPanel)
The admin paths might be restricted or protected via the panel settings.
If you tell me what level of access you have (e.g., root, FTP, control panel), I can guide you more precisely.
