Settings doesn't save

Options are saved in the database but not displayed to the reopening of the plugin

You must add in the menu class or ID – the very first setting – then all the other options will save.

not really, I tried it and it works locally. when I transfer wordpress plugin online and stops working.

try and deactivate your other plugins – possible clash with something else

Nope, the problem is not solved ??

It should work regardless of location; local or production. So on your production site the slicknav settings are not retained when you update settings, and you have menu CSS selector added?

The settings are stored in the database (I checked) but are not visible when I open the plugin.

Yeah, i add the CSS selector but nothing….

In the migration from local to live did you use a db tool that handles serialised arrays like Duplicator or the interconnectIT script or migrate db pro

with another hosting this work properly! the server is Linux PHP 5.6 based…

In the migration i use PHPMYADMIN export/import

Thanks a lot. The problem is the Database Export/Import.
I exported the database again respecting formatting and everything went well

Good to hear
