Oh, I think you didn't understand that I have already uploaded those two files. I'm further along than that. I have already done all that you have described. What I am having trouble with is following the instructions that you are referring to.
I downloaded as instructed. The download was not a zipped folder/file, but instead a collection of folders/files: "adm, includes, language, styles, .htaccess, search.php, and viewtopic.php." My questions in my previous post have to do with the instructions on that page. Please reread it and see if I have made myself clear. The page I am looking at now is
http://humanianity.com/phpBB3/install/i ... file_check
And I have done that "Download modified files archive (recommended)." My questions in my previous post are whether I should now choose that other option (not recommended), namely "FTP upload." Surely I would not do the same thing over again. And there are no other options. But this looks like exactly the same screen that I was presented with that had me "Download modified files archive (recommended)," leaving me with those folders and files in my Downloads folder.
So what do I do now??
update_3-2 is the folder in my downloads folder containing those folders and files listed above.
