For some reason my addons have messed up, the ones I have are working fine but I can't install new ones (ones added or not already installed don't show up) and ones that are installed can't be activated or deactivated
Anyone any ideas? I'm on 4.6.1 and haven't done an upgrade.
Please, check the permissions to the directories needed for the add-on installation. Incorrect permissions can block installation process. Please, see our article about add-on installation in CS-Cart.
