What are the most common causes of an Error 500?

[datarecovee]

The most common causes of an Error Code 500 are corrupt.htaccess files, broken PHP scripts, memory limits (as is the case with WordPress), improper file permissions on the server, database connection problems, or code syntax errors. Basically, this 500 Error Code can be produced whenever any backend script does not execute correctly, which is indicative of a missetting or a bug on the server-side.
