Try going to https://your-site/wp-admin/options.php, search for woocommerce_force_ssl_checkout, you can change it there. Alternatively, you can change it in the database as well I believe.
Hi there,
To answer your questions, the post content only disappear for that particular post (every other page/post was fine).
We used ACF to build some pages/posts.
We did use classic editor.
We made a few changes to the PHP settings on the server to extend the memory etc. The post didn’t save properly because the settings were a bit low. Hopefully, that will fix the issue.
Thank you for your reply!
I’ve figured out what the problem was. There was an .htaccess file of an old plugin (Webp Expess) which was deactivated 2-3 weeks ago and nothing happened until yesterday when I deleted the plugin. But after I removed the .htaccess file, everything came back to normal.Thank you anway!
