Fix WordPress Login Error

The wp-login.php page on https://www.younitedtechnologies.com is throwing the “There has been a critical error on this website” message. I need the admin area accessible again as soon as possible, but the public-facing site must remain untouched throughout the fix.

You will receive direct FTP credentials to inspect core files, themes, and plugins; weekly backups are available if you want to spin up a quick staging copy or roll back anything you change. No plugins or themes were added or updated recently, so the fault may be a corrupt core file, rogue snippet, or database inconsistency—feel free to check error logs and wp-config settings to pinpoint the cause.

What I need from you
• Reactivate the WordPress admin login without breaking the live site
• Identify and patch the root cause so the error does not recur
• Provide a concise report of exactly what you changed

Let me know your price, estimated turnaround, and any other details you require to begin—once I have that, I’ll send over FTP access right away.
