Hi all,
same problem here - when i open the filter i can't click on any of the options, only on OK button to close it. My version of the shop is 1.7.6.4 and it is a fresh install. I have downloaded the pack from www.prestashop.com, set up manually the database and installed it on my own. Even though this problem persists and i can't fix it. I have tried uninstalling the module (the version is 3.5.0), deleted the folder and again instating it but nothing. Same think.
Any suggestions and solution?!
Thanks!
My issue was solved by reinstalling the theme.
