Hi Billy,
Your problem is with the data files.
With your Template, you have 4 "data files":
For all data (except byMonth)
- wt_data_inc.php
- wt_data_intl.php
For byMonth record page:
- wt_month_inc.php
- wt_month_intl.php
As you could see, there is 2 versions of each file:
_inc.php files are regular (English-like) languages
_intl.php are for other languages (Utf-8)
Apparently, your dates need International version.
Hope this help,
Regards,
Jacques
