Resolution

One possible cause is ModSecurity. This is an Apache module that works as a web application firewall. It blocks known exploits and protects from various attacks against web applications. However, sometimes, mod_security may incorrectly determine that a specific request is malicious while it is legitimate.

To solve the issue, ask your hosting company to deactivate ModSecurity via your cPanel to troubleshoot. Some configurations set via this firewall can block the Nicepage Editor. Instead of deactivating ModSecurity, they can check the error logs to determine if a rule of this firewall is not causing the issue.

Memory limits added via this firewall can also prevent Nicepage from working.
