I was reading that Let's Encrypts is currently not working with InfinityFree, so, ¿what free ssl vendor do you recomend me for use with InfinityFree and that work with InfinityFree?
I think any SSL vendor except for Let's Encrypt would work here. I don't have any particular recommendation, just Google for one yourself.
