Hello Alextender,
I apologize for the inconvenience, but your issue has now been resolved. Please check and let me know if everything is working as expected.
Edit:
I’ve reviewed your site on my local PC, and everything appears to be functioning correctly. Please clear your hosting cache, and check if ModSecurity is enabled. If it is, please disable it temporarily, as well as any Web Application Firewall (WAF) that might be interfering.
Let me know if there’s anything else I can help with!
Best regards,
