Hello Abdussammad,
I had the same issue few days ago, I tried my best with almost all the browsers, clear the cache and blah..blah, but the actual issue was, Regex validating some fields on the 1st page and displays the error message in the 2nd page.
The simple solution for this, try shorter First/Last name and then.."Alternate Phone Number Regex Help" message will go away. Once you signed up, you can change your names later in your profile.
Please try and let me know. Hope this helps.
Thanks,
vrhanth
