OK, I thought you did. I probably wasted a whole day on this setup. If I upgraded plans, then there probably would be something else that doesn’t work.
Stored procedures are indeed not supported on free hosting.
As for what that means for your website, that’s up to you to decide. You can either find hosting that does support the stored procedures, or update your website to not use them anymore.
That would be true for any hosting, not just iFastNet’s premium hosting. If you build your website on one setup (a local setup) and the migrate it to a different setup, there is always a chance that something breaks due to a difference. With our hosting, it was the stored procedures. With any other hosting, it could be anything else.
If you want to try your luck with a different hosting provider, then you’re free to do so of course. But “I had problems with free hosting so their premium hosting probably also has problems, and I can avoid that by going to a different provider” is not fair I think.
