    This may be a plugin or theme conflict.

    Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).

    its not working

    Via FTP or your host’s file manager, navigate to the wp-contents folder (directory)
    Via FTP or your host’s file manager, rename the folder “plugins” to “plugins.hold”
    Login to your WordPress administration plugins page (/wp-admin/plugins.php) – this will disable any plugin that is “missing”.
    Via FTP or your host’s file manager, rename “plugins.hold” back to “plugins”
