In order to use my RSS Feed plugin, it requires enabling Exec() or creating a chron job. The message in the Chron job area is that the entire job can’t take longer than 5 sec. I believe RSS does take longer than that. How do I go about configuring my RSS or is that not allowed?
exec() and similar commands definitely are not allowed for security reasons. Creating a cron job should be fine though, assuming you don’t have an enormous amount of feeds (more feeds means more websites need to be checked which means it takes longer for the script to complete).
So right now, cron jobs are your only option and you just have to hope it will work (which it most likely will). Alternatively, you could upgrade your account to premium hosting if you really want to be sure.
