Thank you for your answer,

I wish to show you the table in phpmyadmin but I can't access it and I don't know why, please see the screenshots. 

However, I took a screen of the folder ow_themes and themes I've tried to install are there. It's something, right ? ^^

I've just checked and I can't access phptest.php either, do there is a special manipulation I need to do in order to access it again?

Best Regards,

Niko

Thank you for your fast answer,

Normally yes, I had activated it manually,

Any other suggestion?

Kind Regards,

Niko

I still need to take a look at your ow_base_themes table in order to provide you the solution or further steps to proceed. 

Thank you all for your answers

@Darryl : I will try and see if it changes something.

@Ross : Yes, I was able to access phpmyadmin via this URL, but now it is displayed through Oxwall frame. Should I put those files in a separate folder?

Did someone have the same problem before?

Kind Regards,

Niko

Thank you all@Daryl : I have removed OWD_Nyan but it doesn't change anything.
@Tammy : I am 100% positive that allw_url_fopen is on. Should I touch the include?
@Ross : Yes, it does. I was able to access phpmyadmin before the site intallation and I can't now. I tried to add RewriteCond %{REQUEST_URI} !/phpmyadmin/ to my .htaccess ( I have restarted my server also) but it's not working, does there is a step more?
I can't even access my php indo.
So a simple question : If a have a file on my server which is not inside Oxwall frame work, how can I access it?
For exemple, in my www folder (my root) I have added a directory "my_stuff" and I put a html file note.html, how can I access it?

Thank you in advance for your answers,

I'm alone with amazon S3...

The error page is displayed by Oxwall, it surely have something to do with the site...

Will it change the answer if I put money on the table? Which is the best paying support here in your opinion?

Kind regards,

Niko

I have finally managed to open phpmyadmin, I had forgotten to add :

Include /etc/phpmyadmin/apache.conf

In the /etc/apache2/apache2.conf config file, my bad... -_-

So here is my screenshot of the ow_base_themes 

Is it okay? Do you need something else?

Thank you in advance for your answers,

Best Regards,

I provided help to Niko G and this problem was solved by changing the defaut umask of uploaded files within the vsftpd.conf

Default was 077 and the uploaded theme folder was not readable by oxwall.

Maybe, if it's possible, oxwall can check the permissions of uploaded themes, or plugins, and give a alert if it can't read thoses files, or change the permissions ?

Now the themes are displaying but I can't select it.

I have errors on the theme page but I don't know what to do with it, maybe you can help me?

Please look at the screenshot.

Thank you in advance for your answers,

Best Regards,

Niko
