Howdy -- Hmm, I just wanted to clarify -- are you seeing that issue for new Joomla installs?

Or is it for upgrades to existing Joomla installs?

I see a number of references to similar problems in Joomla when I search for that issue on Google. I'm trying to work out what can be done to resolve that.

Basically I am trying to create a brand new virtualmin site, and install joomla via the script and this is the error I get.

Which Linux distribution and version are you running there? I'd like to try to re-produce this in the same environment, as I suspect the problem is triggered by the MySQL version.

Also, could you share the output of this command:

rpm -qa | grep -i mysql

I am needing to install Joomla 3.6.0 ( I know higher than your install scripts, but I hacked that.. )

But here is the error..... Failed to run database setup script : ERROR 1115 (42000) at line 14: Unknown character set: 'utf8mb4' .

Just did a yum update... and here is the RPM grep...

What can I do... Please help ..










It looks like Joomla is trying to use "utf8mb4" for the database characterset, which isn't supported on the MySQL database version available in CentOS 6.

Now, I see that Joomla 3.x is supposed to be supported all the way back to MySQL 5.1, so in theory it should work.

Assuming that's still correct as of Joomla 3.6, I'll talk to Jamie about how best to resolve that. It may unfortunately take some time though, we're going to have to figure out where in the installation process that's getting set, and if it's possible to change it.

Yes, this is going to be big if I can not find a fix for it.. that would mean upgrading Centos .. OMG ... panic... LOL ..

I would think that the SQL database could have the character set added. But I know it sounds easy. lol ..
