Anyone please give me your wild guess

Which is the plugin? Where did you download it from?

WP Filebase thru WP.
Please don’t tell me to ask on that plugin page support because that proved to be the waste of time.

Did you add that file via the Media Uploader or FTP?

FTP

Just for the future, try to make your post titles a little more descriptive rather than a mysteriously vague “give me your wild guess” title. Maybe “trouble trying to get unsupported plugin to work”.

Pete,
Maybe my title is not so bad considering that, there is hundreds and hundreds of plugins and themes that are not working and there is no support at all for them. Maybe cracking down and removing those plugins would be beneficial to a lot of people. That way maybe there wouldn’t be thousands of questions about bad plugins that nobody really has an answer for it or is willing to look into the problem and provide a decent solution.

Try waiting for more than 14 hours.
