The code can not be captcha

Hi, maqei2014.

Can you copy/paste the shortcode you’re trying to use?

As in the following image links in style

Hi, maqei2014.

Please post the code you’re using, or a screenshot that shows your problem. There is nothing in your last post that shows me the issue you’re having.

You can use this display：
[content_protector password=”1234″][/content_protector]

Use this display a blank page. You can not use CAPTCHA：
[content_protector password=”CAPTCHA”][/content_protector]

Those are properly formed shortcodes. Could be a conflict with another plugin. Are there any error messages on your site or in your logs?

That displays a blank page
The following is a list of plugins I installed:
Google Sitemap
WP-PageNavi
WP Super Cache
Yet Another Related Posts Plugin

OK. What happens when you disable *ALL* plugins except Content Protector? If it works when you do that, enable the other plugins one by one and test the page with the shortcode until it breaks.

Disable all plug-in or an error occurs.
To use the style shown below the line. Why is not achieved?

OK, that looks like a CAPTCHA. Does it not accept the displayed value as correct?

I can do this on the site display style:

Can not do the verification code style

So, you’re saying that they *DO* work, just that you’re having issues with the styling being applied to the forms? You are able to apply different styles to the regular form instructions and the CAPTCHA instructions; it looks like you’ve done that here.
