categories - Error while add Category or Tag in Wordpress

When I want to create a new category or tag on the Wordpress site. I encountered this error.

Empty Term.

As usual, My theme and Plugins are updated. I disabled all plugins. The error was not resolved. I replaced all the Wordpress files and folders with a new version and it didn't fix the problem. I repaired and optimized the database tables and the error was not fixed. I could not disable the theme (enfold)because the site is working.

If you have experienced this error, please help me.

Category tables damaged. Delete wp_terms table and insert them again and problem is solved.

Rename the "plugins" folder in "wp-content" and create a new empty "plugins" folder. Test if the error persists.

Temporarily revert any custom code or modifications in your theme.

Add a higher memory limit to "wp-config.php."

Use the "WP-Optimize" plugin to optimize and repair the database.

Check for error messages by enabling WordPress debugging in "wp-config.php."

Reach out to the "Enfold" theme support team for assistance.

This steps worked for me:

Step 1: Delete Records with term_id = 0 Execute the following query to delete the records with term_id = 0:

in PHPmyADMIN go to your database and run following SQL's. Don't forget to make a full db backup before you start!

DELETE FROM wp_terms WHERE term_id = 0;

Step 2: Add the PRIMARY KEY After removing the records with term_id = 0, you can add the PRIMARY KEY:

ALTER TABLE wp_terms ADD PRIMARY KEY (term_id);

Step 3: Add AUTO_INCREMENT Now you can set the AUTO_INCREMENT property again for the term_id column:

ALTER TABLE wp_terms MODIFY term_id bigint(20) unsigned NOT NULL AUTO_INCREMENT;

Step 4: Check the Changes Check if the changes are correct by running the following query:

SHOW CREATE TABLE wp_terms;

The output should now be as follows:

 CREATE TABLE `wp_terms` (
  `term_id` bigint(20) unsigned NOT NULL **AUTO_INCREMENT**,

  `name` varchar(200) NOT NULL DEFAULT '',

  `slug` varchar(200) NOT NULL DEFAULT '',

  `term_group` bigint(10) NOT NULL DEFAULT 0,

  PRIMARY KEY (`term_id`),

  UNIQUE KEY `slug` (`slug`),

  KEY `name` (`name`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

Step 5: Test Insert New Term Now try inserting a new term again:

INSERT INTO wp_terms (name, slug) VALUES ('Test Category', 'test-category');

If this works successfully, the problem is solved.
