Fatal error Uncaught TypeError ftp_nlist() WordPress

Error: ftp_nlist()

How to fix Fatal error: Uncaught TypeError: ftp_nlist(): Argument #1 ($ftp) must be of type resource in wordpress.

WordPress is the most popular CMS in the world. Most news sites, blogs use wordpress as their CMS.

In addition to the ability of the plugin which is relatively easier for users, the provision of themes is also very large and free.

You can use it as you wish. But while using the plugin, sometimes I run into problems.

Today I’m moving wordpress data from live to localhost but I’m having problems when I save plugin data.

The plugin I’m having trouble with right now is elementor. I want to change the settings to enable the safe mode option, but when I save I get an error ftp_nlist.

Overall this error is as shown in the following text:
