Cause of 500 internal server error when destoon is installed

When we first installed destoon B2B website management system with the error "500 internal server error", the reasons are as follows:

Solution 1: Delete the. htaccess file in the root directory. If it is invalid, try method 2;

Solution 2: For liunx/Unix servers, if the 0777 attribute is not supported, you can modify
Root directory config. Inc. php
$ Cfg ['file _ mod'] = 0777;
Is
$ Cfg ['file _ mod'] = 0755;
Then, the FTP directory and file that has been automatically changed to the 0777 attribute by the system are changed to the 0755 attribute.
