The new update deleted my whole site

Hello Support team:
I recently received the latest theme update in my WordPress panel, it ran and damaged my entire website, my site was completely removed. I installed and restored new backups of the site, but I can’t recover it, please give me special support to know how I can recover my site without this new update interfering. Thank you.

what happen after you restored your new backup? if if it looks messy, check your plugins list first. maybe some have not been installed

Thank you for your answer. My site doesn´t look messy but empty; all my site is empty, no content, nither any module or section is shown. Also, I can´t edit anything because dissapeared the CSS editor.

maybe simply deleting and re-uploading the theme manually will fix your problem.
