I’m sorry, but there is a reason why language is “universal”. So that we can understand each other.
google “define:compatible”. It says:
“(of two things) able to exist or occur together without problems or conflict.”
So, is this plugin compatible (according to universal concept) with the StatPress plugin or not? Will they work nicely together, without problems, or not?
The current code, as-is, is not compatible, because there is this one obvious error. Having it fixed, will the fixed plugin be compatible with StatPress or not? (code-wise, apparently at least, it will. Data-wise is unknown for me)
If it is, then you can check with StatPress authors and see if you guys can find a general way of “sharing” code (using include_once/require_once or function_exists or what not)
