ASP program Most cases are caused by not opening the permission, not the program or database, so if you encounter 500 errors, first check whether your permission is opened. FSO permission, execution permission setting, or program pool setting. PHP program Most cases are caused by code errors, or incompatibility of PHP version code, poor database connection, etc. You can try to switch the PHP version and check the database connection configuration file. Note: ISAPI program settings are also one of the reasons for 500 errors. If you are not clear about ISAPI, do not set it. |
