I'm trying to track down the reason why I am not getting the "upgrade automatically" link under plugins that need upgrading. So I thought I'd try the Update Core tool, and just see what it told me, even though there aren't any updates available yet. This is the error message I get:
You do not have sufficient permissions to update plugins for this blog.
So when I found what causes that mesage to display, I find that it is checking an option called "update_plugins". So I searched my database for those options and get two results in the options table. One is for a row called "cron" and this is what it says:
The problem I'm seeing here is that my tables are prefixed "thdwp_", not "wp_". Not being a programmer, I tried editing these manually, but as soon as I refresh that admin page, it resets back to the default wp_ prefix. Obviously there is some kind of cron job running, or something, I really don't know what all that means.
Of course, the other result is a row called "update_plugins". The information it gives me seems to be a list of all the plugins that need updated, or have been updated previously. I'm not sure.
In any case, perhaps this is enough information for a WP programming guru to help me figure this out. All I want is to be able to install and update plugins from my admin!
