Problem editing the components page in any theme

Costas,

when your GetSimple-Installation is installed in the root of the server,

Code:

RewriteBase /

when it is installed in a subdirectory of the root

Code:

RewriteBase /name of that subdirectory/

but when you have disabled friendly URLs, that is not important

But as I see, your GetSimple is installed in a "subdomain" ZK of the "domain" ellada-mas.com

so I cannot say how GetSimple behaves in subdomains

Can you log into your GetSimple-Administration directly from ellada-mas.com/subdirectory where GetSimple is installed/admin ?
