On Friday, 28 February 2025, important maintenance work was carried out on our homepage between 10 am and 2 pm. Thanks to professional support, the error was found. It was an incorrect entry with brackets and spaces, which was caused by a bad update of the WooCommerce plugin (online shop). The entry could not be automatically corrected by another update, so it was adjusted manually. This led to minor administrative problems in the online shop and the appointment booking portal. Our website has now been online for 4.5 years and has developed steadily over this time. We have done our best to integrate all functions for our members and officials. Nevertheless, errors can occasionally occur due to necessary updates of additional modules. Although these are not visible to the outside world, they cause challenges in menu administration, when customising items in the online shop and in warehouse management, which were not possible before the maintenance work. We would also like to point out that the display error in the Tatsu-Ryu-Bushido mobile app on Android devices and problems with registering for a training session are not due to our homepage. Even the measures taken today have not fixed the error! Users of iPhones and registration outside the mobile phone app (including Android users) should work without any problems.
