name shop in template furniture shop

Why I can't change the name of the shop?
I can change everything but not the name of the shop.
What I have to do?

Maybe you think of title in default menu item (home page). Enter the menu item settings and check parameters on the right.

This is my problem
From the start page of the site www.matahari1998.com on the top menù I click "store" and I go to the store page where the name is "Joomla Fashion Store" under of it there is the description. I want to change name and description. To do that I go joomla-administration > component > virtuemart > shop and I try to edit the shop name and description, I save it and I check the shop page but nothing change.
The same step I do to change "product category" and is work fine.
I don't understand why, may be I make some mistake and after a lot time spending to try without any result I decide to ask your help.
I contact my provider and this is the answer:

Hello,

Thank you for contacting us again.

We have tried to change your VirtueMart shop's name, however I am afraid that we were also unsuccessful in doing so.

As such, we suggest reviewing the official VirtueMart documentation for further information, regarding your issue. Said documentation can be found here:

virtuemart.net/home/manuals

Alternatively, you may contact the plugin developers for further information.

If you have any further questions or need additional assistance, please do not hesitate to contact us.

Kind regards,

I hope you understand my explanation.
best regard

Please edit file /templates/hot_furniturestore/html/com_virtuemart/categories/default.php and change text in this part:

Ohk there is a big problem. I saw a user under shop tab in virtuemart. & I deleted it. Now I am unable to login. How can I solve this. I really need to work on the website. Thats weird because it did not said admin. & I thought I can only change admin users from joomla control panel & not virtuemart.

For such fix you would have to pay us
