What's wrong with OSPanel settings?

Question

PHP

Good afternoon, tell me please, can anyone come across such a thing. When the deployed OkayCMS on OpenServer everything works (in terms of the backend). You can add or remove content. BUT when I transfer to another OSPanel where it is configured as a virtual server, where 5 sites are already working normally and the entire backend is working, then OkayCMS cannot be added information through the admin panel. Writes that Added, but in fact there is no well and clearly in mysqli no.

In a nutshell, everything can be done except adding.
Who met with this?
