Iveth,
I've never seen that issue before. Looking at the source of your page, I can't see that text anywhere. However, I am seeing multiple Open Graph tags.. some from JFBConnect, and some from something else. You should only use one extension to manage Open Graph tags on your site, and this could be part of the problem, though I can't imagine why it would cause that problem.
When I run a page of your site through the Facebook URL Debug tool, it seems to think that the "Account Suspended" text is in the title of your page:
developers.facebook.com/tools/debug/og/o...viaje-viajes-express
Could there be something wrong with what's performing translations on your site, and Facebook is seeing an error message from that?
Let us know if you determine anything.
Alex
