Captcha "Invalid Security Code" Error When Registering

[Webcrawler]

Have been testing it for the last 2 days.  Still getting "Invalid Security Code" error.  It works occasionally with "Standard" Global Cache setting and "session.save_path" commented out.  I have also noticed that after a registration is successful, other following registrations (using different computers) get an error saying "Warning, please try back in a few seconds."  Not sure what it is about.  Any suggestions will be appreciated.

Try placing a comment before #disable_functions.  As each server has different configurations, you will have to test the disable_functions that you use one by one.

I tested by commenting out each one of the disable_functions, but none of them worked.  I either get "Invalid Security Code" or "Try Again in a Few Seconds."  Mostly "Try Again in a Few Seconds."

You are testing this using the full url including www I assume?

[Webcrawler]

Yes.

It's OK. Please make some tests and verify me that everything work properly!
TIPS
- Disable the PHP Functions PHP functions system, exec, passthru, shell_exec.
- Don't use Cache on your elxis website. It's no need for Static or Standard Cache.
