Can't create client account

[lizzie_pui]

As I am only an apprentice in Prestashop I need your help with the following problem: I can't create a client account. In the Authentication page I insert the email address and click Create an account, it opens the page where you insert the personal information and when I click the Register button it redirects me to the Authentication page again without showing any error. 

 

Thank you in advance for your help.

 

the code is:

<!---->   <div class="row">   <div class="col-xs-12 col-sm-6">   <form action="http://www.lizi.ro/en/login" method="post" id="create-account_form" class="box">   <h3 class="page-subheading">Create an account</h3>   <div class="form_content clearfix">   <p>Please enter your email address to create an account.</p>   <div class="alert alert-danger" id="create_account_error" style="display:none"></div>   <div class="form-group">   <label for="email_create">Email address</label>   <input type="text" class="is_required validate account_input form-control" data-validate="isEmail" id="email_create" name="email_create" value="" />   </div>   <div class="submit">   <input type="hidden" class="hidden" name="back" value="my-account" /> <button class="btn btn-default button button-medium exclusive" type="submit" id="SubmitCreate" name="SubmitCreate">   <span>   <i class="icon-user left"></i>   Create an account   </span>   </button>   <input type="hidden" class="hidden" name="SubmitCreate" value="Create an account" />   </div>   </div>   </form>   </div>   <div class="col-xs-12 col-sm-6">   <form action="http://www.lizi.ro/en/login" method="post" id="login_form" class="box">   <h3 class="page-subheading">Already registered?</h3>   <div class="form_content clearfix">   <div class="form-group">   <label for="email">Email address</label>   <input class="is_required validate account_input form-control" data-validate="isEmail" type="text" id="email" name="email" value="" />   </div>   <div class="form-group">   <label for="passwd">Password</label>   <span><input class="is_required validate account_input form-control" type="password" data-validate="isPasswd" id="passwd" name="passwd" value="" /></span>   </div>   <p class="submit">   <input type="hidden" class="hidden" name="back" value="my-account" /> <button type="submit" id="SubmitLogin" name="SubmitLogin" class="button btn btn-default button-medium">   <span>   <i class="icon-lock left"></i>   Sign in   </span>   </button>   </p>   <p class="lost_password form-group"><a href="http://www.lizi.ro/en/password-recovery" title="Recover your forgotten password" rel="nofollow">Forgot your password?</a></p>   </div>   </form>   </div>   </div>   </div><!-- #center_column -->   </div><!-- .row for 2 columns--> </div><!-- #columns -->   </div><!-- .columns-container -->   <!-- Footer -->       <div class="footer-container cs-f-wide-mode" data-animate="fadeInDown" data-delay="200">   <div class="cs-top-footer container">   <div class="row">   <!-- Static Block module -->
