Hi @tallensr ,
You must first delete the plugin via ftp or through your host. Access your site files and under “your-site.com/wp-content/plugins/” delete the imagify folder.
Then you can download the latest version of WordPress on www.remarpro.com, unzip and retrieve the web.config file. You can replace your old web.config file with the new one without any problem. Update access to your admin interface and it’s fixed!
