Magento Extension Fix. Databases won't install.

Need a coder to fix a bug in one of my extensions. Had a coder create an extension. Its about 2.5mb. When you load a certain URL the extension is supposed to be installed. The coder created the extension on my store crisp22.com. It works perfectly on the [login to view URL] host. When I try to install the packaged extensions on other sites it does not work. For example: [login to view URL] works properly. This is the host the vendor installed the extension on. The extension he gave me is missing a few files of code somewhere. I think it is some CSS issues. Maybe a mySQL issue. For example when I access the url: [login to view URL] it does not work. This is from the packaged extension the coder completed and said to upload and access the /vendor folder to install. For some reason it will not install. While its working on my site. I cant get the extension to work on other Magento stores. I have noticed that for some reason the mySQL databases have not been installed after accessing the installation URL. I have a hunch that the coder messed up some CSS files when packaging the extension, but I cant find where. Maybe I am wrong but when I downloaded and replace my ftp files from my [login to view URL] store and put it on other stores it worked properly. But when i try a fresh Magento install then install the "completed" extension it gives the 404 error. Something is wrong or missing in the extension. Since there are so many files in the extension I am not sure where the problem lies. But I know it shouldnt be a big fix at all once you find it. It might be something thats as small as adding a CSS file, URL, or mySQL login. I have a hunch its the CSS file. ## Deliverables Need a coder to fix a bug in one of my extensions.

I have a hunch that the coder put my hosts mySQL info somewhere, but I cant find where. I could be wrong and it might be a coding error instead of mysql. But need someone to fix the installation so I can package the extension and distribute it. If you interested email me at geedubya15@[login to view URL] with a quote. Or if you need more info.

It might be something thats as small as changing a file URL, or mySQL login. The extension must be tested on your own server. You must create your own Magento store's to test out. The final test will be me installing the extension on one of the blank magento stores on your server.
