Hi,
for now this is not supported because this calendar become from static Javascript (not PHP), to change firstday from Sunday do Monday in calendar follow these steps:

- Go into Social Network Admin panel
- Click on "Themes Manager" on left menu
- under "Base Theme" title click on "Social Network"
- Choose on left side "Events/create.ctp" file
- Click on "Copy" Button and select "Blue Theme"
- Return on "Themes Manager" Page and choose "Blue Theme"
- Choose on left side "Events/create.ctp" file
- Edit this template file , you can add this code after line 30:

firstDay: true,

- Save the file

In the steps above, we take care to copy the file into the "Blue Theme" template, this because the basic template is overwritten when you update the plugin.

Fulfilled all the recommendations.
In the fields of "date" when creating events Valid Monday was the first day. Thank you.

But when editing the user profile, such as a birthday, the first day of the week in the calendar - Sunday.

How can globally set a rule to the first day of the week was Monday?
Thanks in advance.

Hi,
at file /administrators/components/com_jsn/models/fields/date.php at line 93 replace add this parameter:

data-date-weekstart="1"

so line 93 becomes:

return '<div data-date-weekstart="1" data-date-viewmode=.........

To fix both problems in next release we will add some language constant (if not already present in Joomla).

Easy Profile strings are parsed by Joomla language manager.

Try to read this post: https://www.easy-profile.com/support/all-default-fields-in-back-end-greyed-out-in-front-end-invisible.html#reply-7337

Line 93 in the file has changed, the cache cleared.
But all the same calendar week begins Sunday

Maybe it somewhere else to be done?

Hi,
strange for me works, post me your site link please, we will check.

I can't see the code (see screenshot)

Sorry so many questions.

No problem . Your question help us to make a best component.

I see another small problem on your site, in the green button on GMap field missing Pin icon, re-download latest version and reinstall, during first hour of release we have re-uploaded a correct version.
