I'm having an issue debugging why the plugin I'm creating keeps displaying the error
You need to upgrade your database as soon as possible....
The work I've done so far has been on a remote dev site, and everything seems to work fine there - with no errors at all. I decided to test what would happen when I throw the plugin into a different environment to see if it would still work fine. Bare in mind that both versions of WordPress are
3.9.1. The plugin has remained the same, but the servers are different. The only other different thing between the two is one is a multi-site (the original dev site), and the other is just a standard WP install.
The first issue I resolved, which was a problem within the way I was creating new tables. For some reason
replace as a field name was fine on the dev site, but on the vps it wasn't. Possibly due to different versions of MySQL.
I was wondering if there is a way to debug what is happening? Why would the database need upgraded?
