Disappeared pages in project

[Usevalad Zhurauliou]

I was on the Jira project pages, it was locked for me. Somehow I managed to connect to my Space but right after that person who had an access told me that there are no more pages created before, I believe they were not connected to any of the space. 
Is there an opportunity to restore them somehow? I didn't have any warnings before connecting another space..

What do you mean by "Jira project pages" and "it was locked"?

What is the connection to the Confluence Space?

You have not told us what you think is lost, and might need to be "restored" - could you explain that more?  What exactly has gone missing?

Jira project pages is — https://tppr.me/MdYVi this
I couldn't see the documents there, because they were locked for me. 

I used three dots on the right side to link this to another space
I didn't know that there was any documents(they were hidden from me)
They disappeared after I linked another space.

That link does not work for me.  Could you attach a screen shot showing what you mean by "Jira project pages" and "locked"?

[Usevalad Zhurauliou]

Ok, that screen is trying to show you pages in Confluence that are linked to this project (plus the line of icons are shortcuts to the templates that might be useful for new pages)

You have not explained what "locked" means to you.  However, my guess is that someone has restricted the pages (in Confluence) you've blurred out so that you can't see them.

I just wanted to show where the problem took place. Yeah, locked means there was documents, but I was restricted to see them, but I was able to click on 3 dots on the right side and relink the space, after this (of course) even though the documents was hidden for me they just disappeared for a person who created them earlier.

Documents that was on this page wasn't created in confluence.

>Documents that was on this page wasn't created in confluence.

That's wrong.  Documents on this page are links to Confluence pages and templates.  I suggest you check the visibility and restrictions on the pages in Confluence.
