After you letting me login and doing some testing…
My conclusion is that your wordpress shortcode is completely broken.
Try installing the WP files again. Manually download the WP install zip file an upload all the files by FTP. That might fix it.

Otherwise ask for support in the WP forums related to installing troubleshooting.

Just a note here for anybode else with same problem, it was WP 3.0.
She did a manual WP re-install.
After downloading the zip file and uploading and replacing the WP files by FTP it now works.

which wp files do I need to upload as i am having the same problem. Will this not mess up the site?

paintersinn,

Always check for a plugin conflict first.
Do this as a test:
Temporarily disable all your other plugins.
Does it work now? If yes, enable the plugins one by one to determine
which one conflicts. Which plugin was causing it?

If it was not a plugin conflict, it can be a WP problem. Some have reported success repairing the WP install.
I do not know which files were the problem. Perhaps you could ask in WP troubleshooting forum.
All the files from the WP install download can be uploaded again by FTP. It is a way to repair missing or damaged files. Do not delete the files that are there, just replace. There can be complications, so it is recommended to backup your files and database first. No warranty provided, proceed at your own risk, etc.

Thank you Mike Challis! I was all ready to replace all my files but did a check on plugins first, turns out it was a plugin called Wordspinner…..deactivated that and all forms and tables came back as if by magic.
I have made a donation to you Mike through your website, it is only small but I just wanted to thank you for your time you took to explain that to me, sometimes this forum can be a cold and dark place! Thank you x x x
