error403.png

error-404.png

The issue may happen on both Joomla and WordPress websites.

Solution:

One of the possible causes is ModSecurity. This is an Apache module which works as a web application firewall. It blocks known exploits and provides protection from a range of attacks against web applications. However, sometimes, mod_security may incorrectly determine that a certain request is malicious, while it is actually 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 Nicepage Editor. Instead of deactivating ModSecurity, they can check the error logs of ModSecurity to figure out if some rule of this firewall is not leading to the issue.
Memory limits added via this firewall can also prevent Nicepage from working.
