Hi @putraecom đź‘‹

That’s definitely an odd error, and I can only imagine how frustrating that would be. Let me try and guide you in the right direction on this one.

I took a look at your error log – it does show some error message from WooCommerce, but those do not seem to be serious enough to cause the issue. They seem to be notifications about a database change.

I understand that your WP-Admin links do not work. In any case, can you try re-saving your permalink structure at WP-Admin > Settings > Permalinks?. Sometimes, that works if it is a simple database issue. WordPress will either create/rebuild the .htaccess file. If WordPress cannot automatically edit the .htaccess file( if it is not writable), then WordPress will provide manual instructions after saving the correct block of code so that you can manually add it to your .htaccess file. More Info: https://wordpress.org/support/article/using-permalinks/

If the Settings > Permalinks link throws a 404 error, this tip will not work (for obvious reasons). If that’s the case, try downloading WordPress again, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), and delete then replace your copies of everything on the server except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings.

Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

I remember reading at least one situation, where there was a file permissions issue for WordPress files. Please log in to your cPanel and check your file permissions to see if they are correct: https://wordpress.org/support/article/changing-file-permissions/

If that doesn’t help either, I would recommend reaching out to your web host and ask them to investigate this in detail.

I hope this guides you in the right direction.

Hi @putraecom

Thanks for doing those tests.

Update: i tried again, fresh install without wp-content, it gives out “No matching template” error”.

This is probably because WordPress did not detect a theme, and is unrelated to the original problem. However, since it still 404ed after setting up a theme, we can confirm that this is not being triggered by the files.

Quick question: Did you try checking if the .htaccess file is correct? Also, as I mentioned in my previous message, did you check if the file permissions for WordPress files are correct? As I mentioned, I remember reading at least one situation, where there was a file permissions issue for WordPress files. Please log in to your cPanel and check your file permissions to see if they are correct: https://wordpress.org/support/article/changing-file-permissions/

The 404 error typically relates to “file not found”, so it is unlikely that this is related to a DB error. I see that you are unable to reset the permalinks from the dashboard (for the simple reason that clicking on any link shows a 404 error). Could you try resetting permalinks from phpMyAdmin? Please follow the steps listed in this article: https://in.godaddy.com/help/update-wordpress-permalinks-in-the-database-26354 – does that fix the issue?
