Recently active problems in PBwiki tagged with url

The Insert Link function doesn't seem to be working. When I click the icon while editing a page the Insert Link box pops up, but it doesn't actually load. I've tried multiple computers with the same results, so it seems to be an issue within pbwiki.

Previously I was able to access my pbwiki page using firefox, but now it can't seem to be able to load up the pbwiki page and keeps giving me "Firefox can't find the server at dsldevice.lan." error.
The page loads up fine in IE. Please advise ><

Whenever I put a URL with percent symbols in the text of a wiki page, the automatic links replace the percent symbols with plus signs. The URL appears correct in the wiki page, but if you click on the link, it tries to go to the wrong address.
Example:
Text says "http://www.pbwiki.com/mysite%tomorrow%schedule"
Link actually directs the browser to "http://www.pbwiki.com/mysite+tomorrow+schedule"

I'm trying to link to content that I do not control, so I can't change the URLs unless I use tinyurl, which I will have to since at present all of my links are broken. Is there a way to fix this bug?
