where is your website hosted at?

You could try using some plugin, and also contact your hosting provider as they might have put some limits on max php execution time.

Try disabling zlib or compression in your Web Hosting. If its disabled then enable and try.

Go to your web hosting file manager and remove the captcha plugin folder. I hope this will fix.

Hi,
