Hi Yame,
The site is up and running like it shuold be, right now we have a "under construcction plugin" active, that is why you see that page in the front-end, I thought you asked me for the login and password of the back-end of the site to login, let me explain step by step what you have to do in order to get into the site with this "under construcction" pluging or any "under construccion" plugin:
Access to the Back-end of our webpage
**********************************************
Step 1 - You have to paste this addres in your web browser ( https://www.roperotienda.com/issi ), as you can see there is no /wp-admin just /issi instead, after this you will be redirected to a custom Wordpress login page.
Step 2 - Here you place the login and password, the ones I pasted in your "Secret information" section below, then you have to hit enter.
Step 3 - After this you will be redirected to the wordpress admin back-end, this is where we installed your theme called "new-boutique".
If you have gotthen this far, you can see we have managed to install and upload the demo site for the theme, everthing here we have been able to unscramble, since there is not much in teh documentation for the theme.
From here you will se a commun worpress back-end instalation, here at the top left corner of the admin bar, you have to click where it sais "ROPERO TIENDA EN LINEA", this will take you to the front-end of our site. Right here you will see what our problem is.
As I wrote before, the ONLY problem we have, is that we don't have any idea where to create, edit, update or delete any of the images or tittles of the categories that are already created for this demo site, this regarding the "Category Menu - Header" that we have selected for our project.
As you can se in the image attached here or the other images I have send before, they all show where the problem is.
Please help us out with this as we have not found a way to overcome this issue. Belive me we have try.
PS (the image attached have been edited in order to show you what we have writen here, the color RED is not part of of the images, just the color we used to mark down what we are traying to tell you)
