Hi @devabdullah

Thanks for reaching out!

I understand you’re having issues with your custom payment plugin after updating to WordPress 6.4.2. This could be due to several factors such as compatibility issues or changes in the WordPress core that affect your plugin’s functionality.

I recommend first checking your plugin’s code for any deprecated functions, as these may no longer work with the new WordPress version. You can refer to the WordPress Codex for a list of deprecated functions.

If the issue persists, it would be best to debug your plugin. You can do this by enabling WP_DEBUG in your wp-config.php file. This will display any PHP errors on your site, which can help identify the problem.

Lastly, you might want to consider getting in touch with some of the developers on the channels below. They can help ensure your plugin is compatible with the latest version of WordPress. The WooCommerce community is filled with talented open-source developers, and many of them are active on the channels listed below:

• WooCommerce Developer Resources Portal
• WooCommerce Advanced Facebook group
• WooCommerce Developer Slack Channel
• Hire a WooCommerce Expert

Hope this helps!
