 * I cant upgrade plugins from certain mainwp child.
    I’ve noticed that mainwp says
   that cannot write the folders, but the folders have full write and read access(
   777)
 * How can I debug this issue?
 * PS: I’ve found that when I go into “connection details” this error appear
 *     ```
       #0 /wp-content/plugins/mainwp-child/class/class-mainwp-helper.php(115): MainWP\Child\MainWP_Helper::check_dir()
       #1 /wp-content/plugins/mainwp-child/class/class-mainwp-clone-page.php(348): MainWP\Child\MainWP_Helper::get_mainwp_dir()

 * I think I’ve found the problem
 * link property is not being initialized from WP_Filesystem_Base (WP_Filesystem_FTPExt
   Class), therefore methods like ftp_nlist and ftp_mkdir are receiving null for
   the first parameter.
 * Essentially, at the moment that $wp_filesystem in file wp-content/plugins/mainwp-
   child/class/class-mainwp-helper.php, line 145 it is NOT initialized, (you can
   trace it down to see that is NULL at that moment):
 * `$wp_fielsystem->link`
 * In my case, I’m using ftpext for FS_METHOD and I’m willing to use it for security
   reasons
 * Solution/Conclusion?
 * I think you cannot simply just call global $wp_filesystem, it must be initialized
   before being used.

 * According to the code, FS_METHOD ftpext is checked during the checkings so technically
   it was compatible at some point and now is legacy code?
 * FS_METHOD direct is too unsafe for my sites.

 * Hi [@sirlouen](https://wordpress.org/support/users/sirlouen/), at the moment,
   the ‘direct’ FS_METHOD is required.
