 To confirm whether a misconfiguration in ''.htaccess'' is the cause of the 500 Internal Server error, either remove or rename the .htaccess file temporarily and then try to reload the page.
+==== Example 3 ====
+The following "Alias" directive in .htaccess will cause 500 on Apache (LSWS will ignore it without returning 500) since "Alias" directive is not allowed in .htaccess.
+  Alias "/" "/home/$USER1/public_html/"
+==== Example 4 ====
+Syntax is wrong for the followintg directive:
+  Header always set Strict-Transport-Security: max-age=63072000; includeSubDomains; preload
+which will lead to "Too many arguments to directive" error in error_log:

+The correct syntax is the following and it should fix the 500 error for Apache:
+  Header always set Strict-Transport-Security: "max-age=63072000; includeSubDomains; preload"
