Make sure to validate your module before you submit it to the Addons marketplace! Indeed, the Addons team will refuse to accept a module that is not at least valid.
PrestaShop official forum
Join our forums at http://www.prestashop.com/forums/, and search for an answer using the relevant keywords. If your search needs refining, use the advanced search form. And if your search doesn't yield anything useful, create a new thread, where you can be as wordy as necessary when writing your question; you will need to register first.
Some forums keep certain threads pinned on top of all threads; they contain some useful information, so be sure to read them through.
Our bug-tracker
If it turns out your issue stems from a PrestaShop bug rather than your code, please do submit the issue in the PrestaShop bug-tracker: http://forge.prestashop.com/ (you will need to register). This enables you to discuss the issue directly with the PrestaShop developers.
