saguaros ok, issue is follows:
If you install the lastest version by uploading, it brings an error message (same as your screenshot), but if you install it via the Joomla Built-in "Install from Web" it installs properly... However, then I get the 0 error... either way...
I deleted the whole installation again and started fresh with the latest Quickstart and then I DID NOT INSTALL THE LASTEST VERSION OF SOLIDRES AGAIN, as I need to finish the site and cannot use it with the error message, I will only install the latest Solidres version, once the issue is resolved, that's the reason I did not share the Admin info...
The same site has another issue with a GK extension which I posted in another thread, and there is the Admin info in, however please do not try to install the latest Solidres version on this site, as that will destroy everything, I did on the site so far...
Thanks
Heiko
