Hi
My question is that= Is OJS works fine with Shared Hosting?
And is OAI is work fine with shared hosting OJS websites?
It depends on some factors, such as the size of the journals in this OJS, the plugins installed, the resources offered by the chosen provider and its security restrictions.
Smaller installations tend to work better, while those with more content may have more difficulty.
I’ve seen a provider where the installation of plugins via the Plugins Gallery didn’t work, and the most common problem tends to be the e-mail sending limit, which can often be circumvented with a dedicated service.
I suggest searching the forum for reports of OJS hosting on providers you would use to see if they recommend or report problems.
