We would like to point out that VieCode Shop 7.2 is not officially considered compatible with WoltLab Suite™ 5.4, although installation or update is not prevented. Compatibility with WoltLab Suite™ 5.4 will not be guaranteed until version 8.0 of VieCode Shop, which is currently under development. Accidental upgrade to WoltLab Suite™ 5.4 is impossible with VieCode Shop 7.2 due to technical security restrictions. As soon as the necessary adjustments by VieCode and Krymo Software are completed, we will inform you again here.
