Hello there, everyone. My name is Lisha, and I work as the company's IT manager. Users don't understand why they get '403 forbidden error WordPress' on their screens. A 403 forbidden error may arise when a server's connection is broken due to improper credentials. The most common causes of this problem are issues with your WordPress site's access policies and.htaccess file. Also, a 403 error may be caused by a plugin problems.
