actually right now im working in my site ive spent about 2 years working on it
and today i did the “upgrade thing” but is nothing more than a overpriced migration to hostinger ok with that.
my questions are:
here in 000webhost i got this free hosting in which i work everyday. in hostinger by what i know right now if i dont pay my account will be deleted?
can i still working for free in hostinger after my “upgrade” plan expires? or ill be forced to pay to keep it up?
000webhost will dissapear with all my work too?
if i work everyday in the ftp and database is there anychance that my account or my website will be lost?
Upgrade - is moving over to Hostinger premium services.
