Go to your WordPress website’s wp-config.php file and check, if you have
define( 'DISALLOW_FILE_MODS', true ); . This stops WordPress from updating any of the WordPress core files or plugin files.
If you try to update your WordPress core, it will give an error saying, “WordPress 6.x.x is available! Please notify the site administrator“. and if you check under the plugins section, you will not find the options to update or delete the plugins, but only the option to activate or deactivate the plugins.
Do not worry, the solution is straightforward. You have to edit the wp-config.php file and change the
DISALLOW_FILE_MODS value to false. This means the code should look like this:
define( 'DISALLOW_FILE_MODS', false);
