Ok so I was stupid enough as to change at wp-congig the define(’DB_COLLATE’, ”); to define(’DB_COLLATE’, ”utf8_general_ci); because someone told me is what I need to be able to write thai, I did it from ftp and the file changed some words, u know, to something like GhnJIjmklHKL.... I needed to use the wp-config-sample to replace it, and now my wordpress is back as how it was 1 year ago. I guess some other files changed the encode also? Also I cant log in as Admin....
And yeah Im stupid enough as not having a backup, I lost the one I had from last month.
Is there any hope left for me? :(
