Bots trying to hack my unfinished site?

Last 2 weeks, multiple bots from different IP addresses keep hitting this particular file.... are they trying to find a hole or vulnerability or just trying to spam in the dolphin script? The file /modules/classes/Config.php simply doesn't exist. Or was it supposed to? In line 63-65 this is it: 

$sClassName = $sClassPrefix . 'Config';
require_once($sClassPath . $sClassName . '.php');
$this->_oConfig = new $sClassName($aModule);

Makes me wonder if I messed up the script a little somewhere. 

[Sun Feb 16 22:50:20 2014] [warn] [client 108.177.231.163] mod_fcgid: stderr: PHP Fatal error: require_once(): Failed opening required '/var/www/vhosts/mysite.net/httpdocs/modules/classes/Config.php' (include_path='.:') in /var/www/vhosts/mysite.net/httpdocs/inc/classes/BxDolModule.php on line 64, referer: http://mysite.net/ 

Please advise. 

if this is in reference to a module, then the url is missing parts. It would normally be (for example):

modules/boonex/groups/classes/BxGroupsConfig.php

or it could b:

modules/boonex/groups/install/config.php

From what you posted, it doesn't look like a bot trying to hit your site, but maybe someone clicked a link that should have gone to a url similar to my first example, but the coding was missing components.

THis is just a guess based on what you have posted so far. Additional information may give better answers.

Error log starting to fill with entries like that so I checked its ip address and looks like honey pot picked it up as possible spammer. More than a few similar ip addresses like that show up in the error log. 

The code you posted looks to be in relation to getting info in regards to a module. This may sound ridiculous, but have you gone through and clicked all links in your site to make sure they all work. I know there are apps out there that can check for dead links and such, but I am old school and tend to do a bunch of things manually, so I spend an hour each day just checking all the links we have.

Also, since you said "Makes me wonder if I messed up the script a little somewhere.", I am guessing you are working on a custom module??? If so, check your sys_modules table and make sure you have a class_prefix for your module, and also check your module's install folder config.php and make sure you have the class_prefix filled in there as well.
