• Forbidden (403) CSRF

Due to its inconsistent compatibilities with web standards, Microsoft's Internet Explorer is specifically not support by MATRR. IE users will mainly experience incorrectly displayed elements on pages, although it is possible for them (while handling forms) to see Forbidden (403) CSRF verification failed error. The error partially depends on local browser settings. So far, we identified this issue with default settings of 64-bit version of IE 6 or higher.

• Go to supported browsers to learn more about alternatives to Internet Explorer including IE plug-in.
