My lists and content within my cards is not showing?

[Cathy Lawrence]

When I open them up to my boards on my desktop,  they only show the header of the card and a summary of how many cards are in each list.  But I cannot access each card/list?  They show up on my mobile, but I cannot properly attach files from my computer?   How can I get the cards to show the full content again?  hopefully, I am articulating this properly, as it has been very frustrating and I need a solution.

@Cathy Lawrence are you able to provide some screenshots or a screencast demonstrating the issue? I don't really understand what you're saying.

This is all I can see within my boards.

@Cathy Lawrence that looks like you have applied a filter:

Look in the top right then click the little "x" to turn off filtering or use the "x" keyboard shortcut:
