We have just released updated version of DJ-Classifieds with a fix for the calendar field in Joomla 3.7 + Google Maps optimization.
After the stable release of Joomla 3.7, we have noticed issues with the calendar in adverts and custom fields.
This version brings the fix for it.
There are also two other fixes applied and optimization for DJ-Classifieds Maps module for a bigger number of regions (10.000+).
You can check the whole change log here.
