Repair WordPress & Stop Spam

My WordPress site — www.vivid.om — has two urgent issues. First, the pages suddenly look scrambled: layouts are off, colours and images sit where they shouldn’t, and overall it no longer resembles the theme I originally configured. Second, I’m being flooded with fake user sign-ups even though I don’t actively offer public registration.

I need a developer who can:

• Restore the site’s normal appearance and functionality without losing existing content.
• Trace and shut down whatever route the bots are using to register, then harden WordPress so the problem doesn’t return (reCAPTCHA, honeypot, or another proven method).

Please plan to work on a live install; I can supply full WP admin and cPanel access. Once you’re done I expect all pages to render correctly across desktop and mobile, and the registration spam to drop to zero. Let me know your preferred approach and an estimated turnaround.
