If errors occur in the interface between Komfortkasse and the shop system, these can be displayed in the Komfortkasse merchant area in the Shops menu item. If a large number of errors occur within a short period of time, a notification is sent to the merchant.


If errors occur for a short period of time and do not occur again after a certain time, they may be temporary errors that can be ignored. This is the case, for example, with network problems or maintenance work in your shop system.


Error analysis

If the error message is not meaningful and only reports an HTTP error, for example, the error message in the log files of the web server on which the shop system is running (e.g. PHP error log) must be determined for further error analysis. This can only be executed on the server of the store system.


Common error sources

Some common sources of errors:

  • Errors in the store software
  • Server error (database error, memory full, etc.)
  • Error or incompatibility in the Komfortkasse plugin, if used
  • Komfortkasse calls are blocked by firewall or similar protection mechanisms(IP addresses of Komfortkasse must be specified in whitelist)
