Back to my original problem with "Birthday" module... You Asked Which PHP am using and I replied:

"Minimum PHP required: 5.2 (my version is 5.2.17)
MYSQL minimum version required: 5.0.7 (my version is 5.0.92-community)
Minimum XOOPS required: 2.5 (my version of Xoops is 2.5.4)
Minimum ModuleAdmin required: 1.1 (my version is 1.1)

The previous version of Birthday worked fine until this latest upgrade to Xoops 2.54
and it has worked well on the other 40 web sites I have up and running. In fact it everything seem to work fine with Xoops 2.51, and in 2.53 see links

"
What's the difference between 2.51, 2.53 and 2.54 where now Birthday does not work properly nor do the updates you did to updated Birthday?

What is your format date? in global.php _SHORTDATESTRING

global.php ----> define('_SHORTDATESTRING', 'Y/n/j');

I use this modue, but had many problems...
i added in admin order date by birthdays or insert.
I fix date format.
I fix download image
i chanche security code with captcha/recaptcha of the core
i added graphic statistics of the birthdays
Now i have only to traslate in english.. and sending.

Thank You ....
