The key to creating a Gutenberg block is to understand its basic structure and correctly connect front and back end resources. 1. Prepare the development environment: install local WordPress, Node.js and @wordpress/scripts; 2. Use PHP to register blocks and define the editing and display logic of blocks with JavaScript; 3. Build JS files through npm to make changes take effect; 4. Check whether the path and icons are correct when encountering problems or use real-time listening to build to avoid repeated manual compilation. Following these steps, a simple Gutenberg block can be implemented step by step.

In WordPress, when adding a custom article type or modifying the fixed link structure, you need to manually refresh the rewrite rules. At this time, you can call the flush_rewrite_rules() function through the code to implement it. 1. This function can be added to the theme or plug-in activation hook to automatically refresh; 2. Execute only once when necessary, such as adding CPT, taxonomy or modifying the link structure; 3. Avoid frequent calls to avoid affecting performance; 4. In a multi-site environment, refresh each site separately as appropriate; 5. Some hosting environments may restrict the storage of rules. In addition, clicking Save to access the "Settings>Pinned Links" page can also trigger refresh, suitable for non-automated scenarios.

To implement responsive WordPress theme design, first, use HTML5 and mobile-first Meta tags, add viewport settings in header.php to ensure that the mobile terminal is displayed correctly, and organize the layout with HTML5 structure tags; second, use CSS media query to achieve style adaptation under different screen widths, write styles according to the mobile-first principle, and commonly used breakpoints include 480px, 768px and 1024px; third, elastically process pictures and layouts, set max-width:100% for the picture and use Flexbox or Grid layout instead of fixed width; finally, fully test through browser developer tools and real devices, optimize loading performance, and ensure response

1. Use plug-ins such as WPCrontrol or AdvancedCronManager to view Cron events directly in the background; 2. You can also view cron key values ??by accessing the database wp_options table; 3. When debugging exceptions, you can disable WP-Cron and set system Cron tasks to improve reliability; 4. Manually running or deleting events can be achieved through plug-ins or adding code. It is recommended to give priority to using plug-in management. Users who are familiar with SQL can choose database operations, and pay attention to the trigger mechanism and the impact of visits during debugging.

Debugging plug-ins can significantly improve development efficiency. The effective usage methods include: 1. Install and enable plug-ins, search and install suitable debugging tools (such as VueDevtools, ReactDeveloperTools), and enable them in the developer tools after refreshing the page; some plug-ins need to be manually enabled. 2. Common debugging operations include setting breakpoints and viewing logs, clicking a breakpoint next to the line number in the Sources panel to pause the execution process, or inserting console.log() to observe key data. 3. Performance analysis and memory check can record CPU usage, rendering time and other indicators during loading, and use the Memory panel to make object snapshots.

To roll back the WordPress version, you can use the plug-in or manually replace the core file and disable automatic updates. 1. Use WPDowngrade and other plug-ins to enter the target version number to automatically download and replace; 2. Manually download the old version of WordPress and replace wp-includes, wp-admin and other files through FTP, but retain wp-config.php and wp-content; 3. Add code in wp-config.php or use filters to disable core automatic updates to prevent further upgrades. Be sure to back up the website and database before operation to ensure safety and reliability. It is recommended to keep the latest version for security and functional support in the long term.
