Text editor not working in wordpress

Hi, I am unable to use the text editor because nothing appears, and when I try and write it is all in white text. This is not the css either. I have tried to change theme, I have tried to use fusion builder, and I have disabled plugins, I also have tried the fixes I could find online such as define(‘CONCATENATE_SCRIPTS’, false ), and nothing works :C My other sites work fine, only an issue with crochetartdesign.com... Please help me. Thank you so much in advance :}

Kind regards,
