403 Error- Forbidden! on form submit

[Macord]

Hey guys I need help here, I receive a 403 Error- Forbidden! each time a form is submitted, I have a.php submitting a form to b.php however b.php throws "403 forbidden You are not permitted to access the requested URL" However if accessing the file (b.php) through the browser directly without submitting the form it loads perfectly it only happens on form submit, both files are owned by the group administrator, both are under the same folder ... any ideas would be helpful

I transferred a Joomla website from another ISP and when it went live on my server, I had all the images on the forum not visible on the forum. I then went and had a look at the permissions and ownerships of the files and folders, and they are fine. I keep getting the error:

403 Error- Forbidden!

The following error occurred:

You are not permitted to access the requested URL
Please contact the Webmaster with any queries.

Any ideas on how to fix this problem would be appreciated

Please check the apache error log, if there are any additional errors. Are you sure you uploaded to the correct directory and not accidemtly to the user website directory?
