Recently active problems in PBwiki tagged with help

I need to restore my wiki to a previous edition. How do I do that?

i can't access to my old pbwiki, not even log in. it's asking me for a password i don ́t have. (fragmentos.pbwiki.com)

Despite some edits this morning, my Recent Activity tab is only showing updates from yesterday and earlier. What's up?

www.wikifoia.org

We use a lot of tables for our pages, and we need the pdf functionality to create documents for people that we don't want looking at our the wiki. Unfortunately, the pdf that is created has a lot of misaligned cells with data in the wrong places. It's ugly...real ugly. Help!

Are tags in languages other than english supported by pbwiki?

I have problems with tags written in greek. Is international tag support a known issue?

Thank you.
