I'm quite new to database and web-design and finally managed to get Joomla up and running on my desktop. Next thing I tried to get Network access and from there on everything went wrong,
To make it short, in the end I removed even the whole xampp setup (apache & co) and made a new setup.
I'm working on Ubuntu 16.04 (as a former Windows user, which doesn't exactly make it easier either...)
and have the latest releases form Joomla (3.7.2) and Xampp (7.1.4) installed.
On the second setup routine I used a different User-name (it seems that was a mistake) and after finishing, it opened up the Joomla-page without problems. But I can't get any access to the admin. Not on the old Site-name or the new one.
In the meantime I have removed Joomla and Xampp a few times (even with the uninstall routine (./uninstall) and nothing has changed. Whenever I install it new, the Bitnami-Installer find the site's name I used in the first place, which is actually ok, but I have got no idea where it get's it from.
Since I have the German version of Joomla running, I can only pass on a free translation of the error message:
Wrong username or password or Account doesn't exist yet...
Summary: I can't access either account. Anybody any ideas...would be really grateful
