WordPress installation fails

Hi,

I cannot get WordPress to run via the plugin (OMV 1.0).

I installed the plugin, then install dB, then activate WordPress, all with default settings.
However, when I click on activate, OMV shows a generic error message.

What is strange though is that somehow, OMV/WordPress notices that I have NAT active on my router. the WordPress link on the plugin page redirects me to the supposed WordPress page using my external TCP port, not port 80/443.

Anyone can give me a hint where to look for an error?

Many thanks

The error message is simply "an error has occured" Nothing else.
When I try to connect to WordPress, it says that it cannot establish a connection to the database.

I removed/reinstalled the plugin and now at least it does not redirect me to the natted port anymore. However, the errors remain the same.

Yes, mysql is indeed not running. I tried to reinstall, but now get the following error when I try to activate. That is after I tried to install a database via WordPress

Failed to execute command 'omv-mkconf mysql 2>&1': Unable to find any database files in /var/lib/mysql. Unable to find any database files in /media/f80ada14-cc76-4aff-8b10-116e668ddb24/mysql/.

Found the issue with mysql. It is now running (I get to the mysql Web interface) , but WordPress DB does not get installed and therefore cannot connect. It is the only db and I can not connect via the Web interface as well

Another update: I managed to install the DB, and where able to activate the wordpress plugin.
I went to the wordpress page and set it up once. Now when I try to connect to it (from outside or VPN), I get 404 page not found.
The plugin page shows that wordpress is active and mysql is running. I am really getting confused now.

Just tried and the page is indeed reachable from inside.
Tested a bit further and if I install it from outside of the LAN, it is only reachable from the outside and vice versa.

Is there any setting that prevents access from other networks?
Routing is OK obviously, as access to OMV is possible from LAN and WAN

Yes, that's why I did not even consider that as an issue.
I can connect to my internal IP from LAN and VPN, and via Dyndns on the natted port from the outside. Only when I tried to access WordPress it fails

Aaahrgh, that's stupid, should have seen that.
Many thanks for your help on this!
Do you know whether there is an option to have multiple URLs, so it works with NAT? I can modify my DNS to get the DynDNS name from inside, but still need to add the port when connecting from outside

I guess I will just change the port for my other application and use default 443 for wordpress then.
Again, many thanks for your help ryecoaaron. You saved me quite a few hours with headaches
