If you have your own website created on the Internet, you may also encounter the 403 authorization error. The reasons may be as follows:
The site was hacked, and as a result of the actions of the attackers, the file with index data was damaged;
when transferring a resource, its data was placed in a storage location with an incorrect address;
Your IP contains data that limits access to the site.
Index files are the records advertising database of the site that the server addresses first when a user requests it, and the rest of its data is processed based on the data contained therein.

For resources that are written in HTML and are static, the index file will have the name Index and the extension html. Dynamic sites have index files with the extension php.

It may turn out that the site distribution is not placed in the top-level folder, but in one of the subordinate directories, for example, with scripts, after which a 403 page error appears. There is no need to waste time transferring data, it is easier to rename the folders.

All actions on the site are recorded by the server with their date and time. Viral code can be easily identified by records such as ?php eval or iframe.
If all the above steps do not help, the only option left is to contact the provider through the technical support service.

To manage the rights required to open the resource, the CHMOD program is used, which has a user-friendly interface. There are three levels of access to each directory and any file on the site:
site owner or superuser;
group of trusted persons (administrators);
site visitors.
Using the CHMOD program, you can set the actions that certain users are allowed to perform on pages and folders:
