I now have access to the backend and site now works fine (as long as I'm just using JOOMLA) except anything having to do with user registration or log-in (since second attempt at installing 2.0.1 appears to have failed as well). Here is where I now stand - receiving error message in CB control panel that pluginsfiles.tgz still exists.
The message states that 'first or second installation step did not take place or did not complete - if sure that first step completed - execute second step - by clicking the link.
How do I know if first step has completed?
I see that there is a newer version available - is it advisable to just try to install 2.0.2? at this point or do I have to first install 2.0.1 without error?
I have tried searching the forums for others with same problem and found a few but none that answer the above questions. Maybe my search criteria did not hit the right stuff
