It often happens that while using the Internet there are various errors. The most common among them is the so-called "500 error" or "500 Internal Error Server".
Causes of Internal Error Server Error
- When in .htaccess files are used invalid structures that cannot work on a particular hosting. Very often, such an error can occur if you use instructions from Russian Apache.
- If the script runs too much time. For the duration of the script, the limitations of the web server apply. For example, if the web server did not receive a response from the script within one minute, then the server will assume that the script is “frozen” and will forcibly end its work.
- If the script wants to get a much larger amount of memory than is possible at this rate. If the script needs more memory, the web server will also force close it.
- If the PHP extensions that are included in the control panel are not compatible with each other.
- In addition, a 500 Internal Error Server error occurs if the web server cannot interpret or recognize the HTTP headers.
Why else can a 500 error occur and how to fix it?
Of course, most often the 500 Internal Error Server error (YouTube and other sites) appears if the incorrect syntax of the .htaccess file was entered or if unsupported directives appeared in this file. In this case, in order to correct such a mistake and bring everything back to normal, it is only necessary to comment on the so-called "Options" directive. To do this, simply put in the "pound" (#) at the beginning of the line - your problem will simply disappear and the 500 error will no longer appear on the server.

But it also happens that 500 Internal Error Server (youtube and other sites) appears for another reason. This can be mainly if you use CGI scripts incorrectly, although this is extremely rare. It is very important to remember that at the end of the line, the entries should not be in Windows format, but UNIX, which is more suitable for the web server to interpret correctly. In order to prevent errors, you need to upload CGI scripts to your server via FTP in ASCII mode. It also often happens that incorrect HTTP headers are generated in the response of the CGI script. If this happens, then you can solve this problem very easily, just refer to error-log.
