Thanks for the swift reply.
I just reinstalled PHP 5.2.9.1, and figured out how to make it an ISAPI installation.
I completed the installtion, but noticed that on the final installer page that there was an error notice: "curl not init".
Then, when I tried to enter the admin page, I saw that on that page, and on all other pages, the page has both at the top and at the bottom the following error message:
Notice: The template file "C:InetpubSiteswww.air.tziona.comlibskinsCURRENT_SKINheader.tpl" doesn't exist in C:InetpubSiteswww.air.tziona.comcoreclassesTemplateSet.class.php on line 206
Also, there is only an ugly white boackground (I assume related to the error messages)
Finally, trying to save an avatar fails. I get a blank white screen with the above error message regarding header.tpl not being found.
Now what???
