CMS Made Simple Forums

I just installed CMS Made Simple 1.2 and installed a few modules that seemed interesting when all of a sudden I noticed the site was now showing:

We are currently experiencing technical difficulties. We will try to fix the problem as soon as possible. Sorry for the inconvenience.

I then enabled debugging and found that I got a lot of similar errors:

Notice: Undefined index: pdf in /homepages/.../modules/Printing/action.default.php on line 33

These all contain:

$params["pdf"]

So it is obviously a problem with PDF and the printing module, but I wasn't able to find any information about this issue or a PDF module.

Any help would be greatly appreciated.

I've fixed the problem in the printing module, but the module that is generating the 'technical difficulties' message is 'error emailer'.... try disabling it.
