Hello,
I have a problem with the page user profile :  it block or load in 5- 10 min. I have 8 country installed with all city.

 After I choose a region and want to choose the city I have all city from all country.

If you know what I can do in this case.

Thanks for help.

The website is xannia.com

Thanks for reporting, this is caused by loading everything at once.
Please go to user-profile.php and do this:

Find this code:
<div class="row">
  <label for="country"><?php _e('Country', 'sofia'); ?> <sup>*</sup></label>
  <?php UserForm::country_select(osc_get_countries(), osc_user()); ?>
</div>

above this block, place following code:
        <?php $user = osc_user(); ?>
        <?php $country = Country::newInstance()->listAll(); ?>

        <?php 
          if(count($country) <= 1) {
            $u_country = Country::newInstance()->listAll();
            $u_country = $u_country[0];
            $user['fk_c_country_code'] = $u_country['pk_c_code'];
          }
        ?>

Now find this block:
              <div class="row">
                <label for="country"><?php _e('Country', 'sofia'); ?> <sup>*</sup></label>
                <?php UserForm::country_select(osc_get_countries(), osc_user()); ?>
              </div>
              <div class="row">
                <label for="region"><?php _e('Region', 'sofia'); ?> <sup>*</sup></label>
                <?php UserForm::region_select(osc_get_regions(), osc_user()); ?>
              </div>
              <div class="row">
                <label for="city"><?php _e('City', 'sofia'); ?> <sup>*</sup></label>
                <?php UserForm::city_select(osc_get_cities(), osc_user()); ?>
              </div>

Replace it with:
              <div class="row">
                <label for="country"><?php _e('Country', 'sofia'); ?> <sup>*</sup></label>
                <?php UserForm::country_select(Country::newInstance()->listAll(), osc_user()); ?>
              </div>
              <div class="row">
                <label for="region"><?php _e('Region', 'sofia'); ?> <sup>*</sup></label>
                <?php UserForm::region_select($user['fk_c_country_code'] <> '' ? osc_get_regions($user['fk_c_country_code']) : '', osc_user()) ; ?>
              </div>
              <div class="row">
                <label for="city"><?php _e('City', 'sofia'); ?> <sup>*</sup></label>
                <?php UserForm::city_select($user['fk_i_region_id'] <> '' ? osc_get_cities($user['fk_i_region_id']) : '', osc_user()) ; ?>
              </div>
