Fatal error: Class 'JLog' not found

[Nunzio2012]

I've been trying to install Joomla! and had a few other fatal errors but up to now have managed to find the corrupted file and re-upload it successfully. This one has me stumped, however. I am completely new to Joomla! so please use the simplest terms possible and be as detailed as possible with any instructions.

So here is the error message I get:

Fatal error: Class 'JLog' not found in /www/zymichost.com/n/u/n/nunziosnj/htdocs/libraries/joomla/environment/request.php on line 22

So I went to the libraries folder, then the joomla folder, then the environment folder and checked the request.php file. I'm using FileZilla. The file isn't corrupt, it fully uploaded correctly. So I checked line 22 of the file which reads:

JLog::add('JRequest is deprecated.', JLog::WARNING, 'deprecated');

So I'm at a bit of a loss as to what is going on. Any ideas? Any other details needed to figure out what's going on?

According to the error message, the class JLog is not found. This class is defined in libraries/joomla/log/log.php which file must be missing or corrupt.

Ah, thanks. See, I wouldn't have known to look there. As a tangent to this, how does one know where these classes are defined? Just in case I come across any other class errors since it seems filezilla has screwed up a hand full of the files. I want to know where to look without having to go through each file to make sure it uploaded correctly. (Which I'm worried I'll wind up doing anyway just o make sure, ugh!)

If you use an FTP client like FileZilla, you can check the number of failed transfers.

The PHPXref application produces a cross reference listing which has all the information where classes and methods are defined, and where they are referenced: http://phpxref.sourceforge.net/

okay, thanks! I did already re-que and re-upload all the failed file transfers but it seems some of the files were corrupted when they uploaded. I'll just try and find all the corrupted files and re-upload them again. Thanks again.

Your best bet at this early stage is to re-upload ALL the Joomla files to replace the items in the joomla_root/ - better now than keep finding problems as you go along.

Unless the problems continue (when it would be best to re-run the installation from the start on a clear server and database) do not upload the /installation directory again as it is not needed.

Do not use a Windows own archive manager to unzip the Joomla! archive in the first place, use 7-Zip or similar.
