I upgraded to Yosemite with iWeb already on my computer when I upgraded, so iWeb is still installed on my computer. However, I am having a different problem.
I created about a dozen sites using iWeb. Rather than using one big iWeb file that had multiple sites, I created a different iWeb file for each of my site (each ending with the extension .sites2). Whenever I wanted to work on any one of them, I would navigate in Finder to the location of the site I wanted, double click on it, and it would open in iWeb.
Now, however, no matter which iWeb file I click on, it only opens one of my sites. In the Finder Preview window, I can see the thumbnail graphics of each of the sites, and they correctly correspond to the site I want. But no matter which one I click on, it only opens one iWeb file (the one I used most recently before upgrading to Yosemite, I think).
In the Library>Application Support folder, I have an iWeb folder (which contains a .sites2 file), and iWebSites folder (which contains a sitenames.xml file), and an iWebTemp folder (which I think I created at one point and contains a .sites2 file). However, none of the files in those folders correspond to the file that is being opened by iWeb.
Help! How do I open my various iWeb files, now that I'm in Yosemite environment?
