user profile update not working - Joomla! Forum - community, help and support

i researing couple of hours , can not solution... on local webserver works fine. on live server not work. website 1:1 same.

in fact there 2 problems:

my 1. problem is: if user logged in , wants edit profile, dropdownlist of timezones, can select preferred timezone. default select item should blank instead there follow:

code: select all

<option value="joption_use_default">- use default -</option>

on local server looks follow:

code: select all

<option value=>- use default -</option>

the problem is, store

code: select all

joption_use_default

database on live server (on local server works perfectly). when go yoour profile, joomla wants convert

code: select all

joption_use_default

timezone, of course not exist... error page.

i saw there no default timezone set on live server in php.ini, not have access php.ini file, tried .htaccess solution, di not make difference:

code: select all

php_value date.timezone "europe/zurich"

.

my 2. problem is: when click save profile, stores in database table: user_profiles following entries:

code: select all

user_id key value ordering
78 profile.address1 "" 1
78 profile.address2 "" 2
78 profile.city "" 3
78 profile.region "" 4
78 profile.country "" 5
78 profile.postal_code "" 6
78 profile.phone "" 7
78 profile.website "" 8
78 profile.favoritebook "" 9
78 profile.aboutme "" 10
78 profile.dob "" 11

the problem here is,

code: select all

profile.dob ""

not valid date string, create other error , of course not nice have written in profile

code: select all

""

. on local server, if user did not enter values, not write table user_profiles.

i have tried find piece of code responsible that, looks impossible find right spot.

how can rid of this?

not sure got code.
in 2.5, code in root/components/com_users/models/forms/frontend.xml

code: select all

<field name="timezone" type="timezone"
            label="com_users_user_field_timezone_label"
            description="com_users_user_field_timezone_desc"
         >
            <option value="">joption_use_default</option>
         </field>

therefore "use default" sets empty value.

what php version of live server?
