You must remove the date format from the preferences!

It doesn't make sense to suggest a date format in the module preferences! If you use a multilingual site in English and French, the format will be the same for both. The format is not the same in these two languages. We have to let xoops handle this and remove this option from the preferences. We can add a define in the translation if you wish to have a personalization.

It was originally developed by Zoullou from France, so I guess, it worked for him.

But I see you point, and it would make sense.

However, I won't have any time to do any enhancements to modules, as my goal was to make them work in PHP7 and fix bugs, and there are several other modules that I need to update for PHP7 and namespaces, like XoopsTube, and few others.

So if you or somebody else would like to make this enhancement, please do.
