I have been using this plugin since 2014 when it was first released - at that point i had about 30 sites in WP with different themes installed which were all working fine but would not respond to any changes made via FTP or SSH so they just ignored me! The team behind mangewp solved my problem then (i think) as far back ago now anyway!! They did such great work getting everything up running again after almost 10 years without issues too.
So much better than other plugins out there even today still being used from 14-15 yrs old versions etc who knows what else might be included?
