I've been experimenting with c5 to see if I want to use it. I'm a total newbie.

When I click the link at the bottom of a page to edit it, recently no edit buttons appear at the top of the page. I'm wondering whether there's a security hole and someone has taken over my pages. Here's why. When click that link, I get an error in the web console showing that page_controls_menu.js contains this line:



Moreover, looking directly into page_control_menu.js, I find that that line never occurs, but that it starts with a huge eval:



etc. I base 64 decoded the big long string and it looks really suspicious, containing lines like this:



My guess is that eval injects troublesome code into the javascript file. Have I been exploited somehow? How can I lock this down? Even if I solve the permissions issue, how can I clean out my scripts of this stuff? Thanks.
