I don’t understand most of what you said. I can give you the plugin if you want to check the code. If you edit the actual plugin, will the custom code get removed once you update the plugin?
No, I just got hosting with cPanel. About the nameservers, I haven’t changed them since I switched hosting, is this something I have to do or is it automatic?
EDIT: btw, in my database, there is a file in the wp_options that has the wrong directory: a:5:{i:0;s:67:”/home/content/67/11759467/html/wp-content/themes/flexform/style.css”
