I am creating a contact form using Contact Form 7. I use Recaptcha to prevent spam, but because of this, Recaptcha.js always comes up in Pagespeed Insights in “Eliminate render-blocking resources” or in “Reduce unused JavaScript”. Therefore, I researched and implemented a method to prevent Recaptcha.js from loading on pages other than the contact page. Try putting the following code in functions.php.

function block_recaptcha_badge() {
 if ( !is_page( array( 'contact-me' ) ) ) {
 wp_dequeue_script( 'google-recaptcha' );
 wp_deregister_script( 'google-recaptcha' );
 add_filter( 'wpcf7_load_js', '__return_false' );
 add_filter( 'wpcf7_load_css', '__return_false' );
 }
}
add_action( 'wp_print_scripts', 'block_recaptcha_badge' );

If you have multiple contact form pages, you can increase the array(‘contact-me’ part, like below.

array( ‘contact-me’, ‘contact-me’, ‘contact-me-3’

Boost your WordPress site’s speed with these steps:

• Hosting & Themes: Choose optimized hosting and lightweight themes like Astra.
• Image Optimization: Compress images with tools like Smush or ShortPixel; use WebP format.
• Plugins: Keep only essential plugins, update them regularly, and avoid overload.
• Caching: Use WP Rocket or similar plugins and enable browser caching.
• Database: Clean junk data and schedule regular maintenance.
• Code: Minify CSS/JS/HTML with Autoptimize; use plugins for custom code.
• External Requests: Prefer system fonts and minimize external scripts.
• Ads: Optimize ads with lazy loading and asynchronous delivery.
• Extras: Enable GZIP compression, use a CDN, and monitor performance with GTmetrix.

Fast sites lead to better user experience and higher SEO rankings.

Examples of My Past Mistakes:

Using the structure “%category%/%postname%” led to issues where only one post would appear if it belonged to multiple categories, and changing a category would alter the permalink.

Current Recommended Settings:“/post/id/%postname%”This avoids duplication with category pages and can accommodate custom post types.

Points to Note:

• Avoid using Japanese URLs.
• If the title is in Japanese, manually change the permalink to English.

With this setup, you can manage categories flexibly without negatively impacting SEO.

I run another site and use a paid plugin called Intagrate Pro. There is also a free Lite version, so you should try using Lite first.

The following error occurred when I turned on the “Force WP User Sync” setting.

Error! This site has the force WP user login feature enabled in the settings. We could not find a WP user record for the given username: abcdef

This error is triggered when a member account doesn’t have a corresponding WP user account. So the plugin fails to log the user into the WP User system.

Contact the site admin and request them to check your username in the WP Users menu to see what happened with the WP user entry of your account.

The site admin can disable the Force WP User Synchronization feature in the settings to disable this feature and this error will go away.

You can use the back button of your browser to go back to the site.

On the other hand, when this setting was removed, when logging in using the Simple WordPress Membership shortcode,

[swpm_login_form]

a problem occurred where the login was not recognized and paid articles could not be viewed.

Solution

• Disabled Wordfence Login Security plugin
• Disabled the “image authentication” setting of the Siteguard plugin

Now, even if “Force WP User Synchronization” is checked, no errors occur and paid articles can be viewed normally. This shows that Simple WordPress Membership members are stored on a separate system from WP users. Therefore, I understand that the setting to sync with WP users in Advanced Settings is important, and that it is necessary to check “Force WP User Sync.”

Summary

If you encounter an issue where you are being treated as if you are logged out even though you’re logged in, first check the “Force WP User Sync” settings. Next, it’s a good idea to verify whether there is a conflict between plugins. In my case, the Wordfence Login Security plugin and the Siteguard plugin were involved.

While plugins are useful, they can sometimes cause unexpected problems by interfering with each other. It is important to create the optimal operating environment while checking detailed settings and compatibility.

If you want to use W3 Total Cache but have installed the WooCommerce plugin, I will introduce settings to prevent customer information from being cached.
