This is a website that was left untouched for the past 5 years. You are correct about the PHP. The site is running on PHP 5.2.17. SiteGround’s fix seems straight-forward, so I will backup the site/database and try their upgrade.
I apologize about the “Etc.”. When I was typing my initial request, Slim Plus wasn’t showing up at all. After a few minutes, it showed up fine. When I last left the site, the links “Submit New Entry” and “Add My Directory Entry” weren’t displaying. I think the Avada theme is creating a lot of glitches; it is a monster.
