I don't have shell access. I have never done anything with cron scripts. My cPanel has a Cron Jobs section that has frequency fields and a command field, but am unsure exactly what to enter. I should mention that there are other databases on my account, like for a phpBB forum. There are a couple of different PHP versions assigned.
I doubt that I can get much help from my hosting service. Another company bought my hosting service and now has lousy support. There is no longer any phone support
My Wikis have pages with code examples and newer versions of the Wikis changed the GeSHi SyntaxHighlight highlighter to requires the installation of Pygments, which broke my highlighting. The new hosting service refuses to install Pygments. I do not bring this up to ask for help with that, but just as an example of how unhelpful their support has been. The previous company had great support.
