OpenCart Community

Today at once in all 3.0.3.x sites no longer possible to scroll in all extensions. e.g. shipping methods.
In firefox developer I get a 404 GET
https://mydomain.nl/cdn-cgi/challenge-p ... c42f1b94d5
[HTTP/1.1 404 Not Found 131ms]

me too, same issue, its not just you.

Yup, there is an issue with OpenCart's server using CloudFlare since the Extensions page is supposed to retrieve the ads/promotions that are to be displayed at the top but CloudFlare is causing the response to be tampered.
