There has been a crash on my wordpress site. I am using a child theme made from Easel them. The site crashed with mingle plugin. The site surface is ok but I can't sign in. I think my only option now is to use FTP. I know how to connect to the site with FTP but I don't know how to enable the wordpress core sign in and sign/register.
Please somebody help me if not I will lose all I have worked for.
