Based on the error notices provided, it seems that the website is experiencing some technical issues related to undefined constants, indexes, properties, variables, and modules. The site may have a front office connection or module that relies on specific language settings but cannot find them properly. Additionally, there are references to year, month, and current date variables that are not defined correctly.
Without further context or information from the cleaned HTML text itself (which is missing), it is challenging to determine the exact content or purpose of the website.
