unable to log in or register on pligg site

[worldwalker]

i need to use an older version of pligg to use the desired templatee, in this case the" Fusion" template that is compatible with pligg 1.0. i have installed and reinstalled that version 5 times now, and every time it installs just fine, i create a "god" admin account. i check trouble shooting. when all is well and installed i go to my home, and i cannot log in. i fill in credentials, press log in, it reloads the page as if i was logged in, but nothing happens.

and this happens in the wistie template.

i have tried installing 1.1 just to see if it would work, but no go. i simply cannot log in. i also tried using the "/login.php?return=/admin/admin_index.php" in case the site just did not showed me as logged in. i searched the forums here and found some people had solved this problem before by adding an older version of "login.php" and overwriting the one in 1.0.

i cannot find any versions older than 1.0, and using the one from 1.1 does not work. neither does using one from the newest version of pligg. if i installed the latest version of pligg or even 1.1.1 login works just fine. problem is only with the 1.0 and 1.1 versions. and 1.0 is the one i need..

someone has a good idea what i could try next?

i am all out of ideas here.

thanks

My idea is to install the template in 1.2.x (latest version).
Figure out which files you are missing, difference between wistie (1.2.x) and fusion.
Copy those files from wistie (default template, 1.2.x) to the fusion template.

Let's see if there are some troubles after that.
