Visual Composer: from offline to online issue

Hi,
I set up a website using Visual Composer working offline with XAMPP then putting the website online using the “blue velvet plugin”. The problem I face after uploading the website online is that I could see every pages as a visitor but some little things are lost (i.e. a little header, some text color….all edited with Visual Composer). I checked the front end and tried to edit a page but Visual Composer didn’t show the page as it was, instead it gave me the message “you have blank page. Start adding content or templates” like the page didn’t exist but I could see them online.

So the page exists but Visual Composer can’t see it.

I followed the codex moving wordpress instructions using “Velvet Blues update URLs” and the “Search and Replace for WordPress Databases Script” but nothing changes.

What do you think the problem could be?

Thank you in advance
