The error occurs in 'admin.versionverificationtool.php, line 12:

 
 10         require_once('controller.php');
 11         
 12         $controller = new VersionVerificationToolControllerHome();

The class 'VersionVerificationToolControllerHome' is defined in controller.php, but it's obviously not getting loaded.  Change line 10 to:

 require_once(JPATH_COMPONENT.DS.'controller.php'); 

This appears to be the proper Joomla way to include this file.

That's odd.  It works on my sites.  I wonder if it's because I have . in the PATH and possibly you do not?

Either way, thanks for the fix, yolabingo!

ken, can you confirm that this fixes your issue?  If so, I will update the code and put out another version.

Thank you both for helping!

Yes, that did indeed fix the issue. 

And given that it's the full path, I wouldn't think the . would be necessary, but perhaps it is.  Since this is a live site, I'm somewhat reluctant to test it.  <!-- s:-) --><img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":-)" title="Smile" /><!-- s:-) -->

Thanks!

I actually meant that the PHP include_path had . in it (meaning the current directory).  If I go to Help -> System Info and look on the PHP Information tab, I see this:

include_path    .:

I'm guessing that is why it works on my server.

Either way, I want to change the code so it works for everyone.  I modified the code and I'm packaging version 1.3 and will have it up shortly.

Thanks for finding and helping fix the issue!

I just uploaded version 1.3.  If you have some time, can you get it and make sure everything works properly on your system?

Thanks again for all the help.

While debugging this, I confirmed that "." was in the path.  However, PHP considered the current working directory to be elsewhere (I think it was "administrator/").  Since there was a file named "controller.php" in that directory, it would happily load that file and proceed. 

We used this component on numerous sites, and saw this problem on about 1/5 of them.  I suspect that the loading of another component played a role.  This change does fix it in any case, and seems like a good disambiguation that is used by most other Joomla components.

Sounds good.  Thanks for helping us fix it for others.  If you have any other feedback, we're always listening.
