Janett Posted April 3, 2019 Share Posted April 3, 2019 This is only warning not error. Update to PrestaShop 1.6.1.23 and this should be fixed Link to comment Share on other sites More sharing options...

Update to PrestaShop 1.6.1.23 and this should be fixed you can fix it by making few changes in database table go to ps_configuration and search for PS_CIPHER_ALGORITHM and change value from 1 to 0. and save will work 1 Link to comment Share on other sites More sharing options...
