I installed an auction module http://addons.prestashop.com/en/marketplace-prestashop-modules/7197-auction-product.html. Then I uninstalled it, made some changes, and tried to reinstall. It was not shown in modules listung, although Presta said the module was installed. The files where present at /modules/auction, but in ps_modules table I can't find it. Then I tried to reinstall the original version - without any changes - with the same result. The module seems to be uploaded, but is not installed. How to solve this? Using Presta Shop version 1.5
