Hi,

I have been working with dompdf since yesterday. I work with a LAMP environment. In some cases XAMP behaves different than LAMP, so you might have different problems.
This is what I encountered, and how I debugged it.

1. make sure that apache has rights to access dompdf
2. make sure your path is set correctly within your plugin (I don't like plugins, so I made it a library, but it makes no difference).

I tested it by 'echoing' hello world and exiting the script/object.

So the dompdf class was initiated and I tried to create a pdf by sending a stating HTML document to the class. That was when I got errors. By searching the internet on the error I found out that the default memory of 16M was not enough.
In my php.ini I changed the 16M for 1000M witch might be a slight overkill ;-) , but it worked. Someware between 16M and a 1000M will be enough.

I hope this will give you some pointers to solve your problem.

gr.

Stommert
