That is not the point. This error you showed must have occurred because I removed the site.pro manually, since there is no official option to do this. I had to restore, and the site came back. The problem is the lack of option (see attached image) to run the OSClass index.php, in my case.
And there is also another problem. The index.html I made in Dreamweaver is not respected, and is always ignored to make room for the site.PRO index, which I did as a test, and now it doesn’t come out anymore!
Ou eu estou acessando o caminho errado, já que eu já pesquisei, mas ainda não encontrei informações aqui no Infinityfree sobre qual seria o caminho certo.
Or I’m accessing the wrong path, since I’ve already researched, but I still haven’t found information at Infinityfree about what the right path would be.
When I check http://resende.wuaze.com, I still see a Site.Pro site. OSClass appears to be setup in a subdirectory at http://resende.wuaze.com/osclass/. Installing your website in a subdirectory is fine if you want to host another website as your main page, but if you only intend to host osclass, I would suggest removing all the Site.Pro files from your htdocs folder, and then moving the contents of the osclass folder into the htdocs folder itself. That way, you can access your OSClass site at http://resende.wuaze.com/ instead of http://resende.wuaze.com/osclass/.
I don’t know where you got the URL http://resende.wuaze.com/osclass/oc-includes/osclass/installer/index.php from. If you were looking at the list of files in the file manager, I suggest you don’t and just follow the installation instructions, because the URL to the installer might be completely different from the location of the source code.
Finally, it seems that Softaculous also has Osclass in their catalogue, so it might be easier to install your website with Softaculous than do the manual installation. If so, you can ignore everything I said, delete everything in the htdocs folder, and install Osclass with Softaculous.
Thank you very much, Admin. I actually tried using Softaculous, but I couldn’t find OSClass. After a new attempt now, I found it, and managed to install it. Grateful.
