I work with PrestaShop since 2011 and PrestaShop 1.3! I love PrestaShop and i love helping other people. I write technical documentations, articles, helps, videos and provide support in about our PrestaShop themes.
All those modules are tested and compatible with the latest versions of PrestaShop 1.7.x. If you find other useful modules, include them in the comments. Here is our 2019 top 10 free PrestaShop modules list.
