Fatal error: Class 'phpBB' not found

[Angelica]

I'm sure someone of you here might remember me form yesterday morning. I'd messed with some of the php coding and because I wasn't the one who installed zen cart onto my site, couldn't find the original code for one of the documents I was using. After finding being pointed to it, I thought I'd do a few updates and as usual, I messed something up.

I had downloaded a copy of the working site to my desktop, just in case I did something wrong, so as soon as I realized I'd messed my site up, I simply deleted and transfered the working site stuff back to where it should be. BUT now I'm getting this error:

Fatal error: Class 'phpBB' not found in /home/mymissio/public_html/includes/autoload_func.php on line 79

I haven't be inside the folder it is talking about, so I don't know what I've done. I've taken a look at the code and the line but nothing is wrong. If anyone could give me some insight on this, I would greatly appreciate it.

I would edit the above but I didn't see an edit button.

The red can be replaced...

I completely replaced the parent folder this was in with the original working site folder,...

Sorry for the multiplicity of posts, but I forgot to mention that I did look at https://www.zen-cart.com/tutorials/index.php?article=82 that page and neither of those were the problem. I didn't do any customizations and was using the original downloaded file for my version, and each of the files was transfered correctly with content; thus, I did what I did.

I'm not clear from your posts whether you resolved your problem or not.
I suspect that it's failing because you've got a bad upload of one or more files in your /includes/classes/ folder. Failed uploads are not uncommon, esp with some FTP programs. You want to use an FTP program that draws your attention to any failed uploads so you can retry them, instead of simply skipping them and moving on to the next file blindly.

I just resolved the problem. The guy who helped me install it said

"They have a file that they originally named class.phpBB.php that they renamed class.phpbb.php without the capital BB. Apparently when you copied the files back over it took the phpBB file out. I just copied the file and renamed it with the capital BB and put it in the same folder in /includes/classes/ ."

Thanks for your insight though, and sorry for the confusing posts.
