There are a few ways to fix syntax errors in WordPress:
1. Access your site via FTP and navigate to the file that is causing the error. Once you have located the file, open it in a text editor and fix any syntax errors.
2. Use the “WordPress Debugging” feature to identify and fix syntax errors. To enable debugging, you will need to add the following line of code to the wp-config.php file:
define( 'WP_DEBUG', true );
This will display any errors on the front-end of your site, making it easier to identify and fix the problem.
3. If the errors are in the database, you can access and fix them using a plugin such as “WordPress Database Error Fix”. This plugin can fix syntax errors in the database, as well as repair and optimize it.
4. If none of the above methods work, you may need to restore a previous backup of your site. This will revert your site to a state before the error occurred and will ensure that your site is up and running again.
Note: Always remember to take a backup before making any major changes to your site to prevent data loss.
