I'm trying to install Stripe in EasyStore, but I get the error: “Invalid installation file”. I expected Stripe to install successfully.
I tried the suggested fixes—refreshing the Joomla EasyStore cache to load the latest payment-plugin list and retrying the installation—but the problem persists. Updating to EasyStore 3.0.1 after taking a full site backup was also suggested if my version was older; the suggested fixes didn't solve it.
