My website has been hacked on several occasions and I have deleted pages, and users. I am wondering if I deleted my theme and reloaded it, if everything I have done, all the custom CSS and extra coding will be lost. As well as featured images and sliders. Please let me know so I can reload my theme if necessary. Thanks
If you have customized the code without making a child theme then all your custom code will be lost. If you are making the child theme and customized the code then nothing will be lost. Relating to Custom CSS, featured images and slider if you reactivate the theme then nothing will be lost.
