A few small code bug fixes needed

My personal site [login to view URL] needs a few coding bug fixes. I would expect an experienced PHP / HTML / Javascript web designer to resolve these issues fairly quickly: [1] The sites Blog and Updates pages display 'empty' posts. This needs fixing. - Check previous pages on the Blog: [login to view URL] to see what I mean [2] The submit and preview buttons for the site's forms work fine in Internet explorer, but not other browsers. This needs fixing. These include: 1. artwork display page(s), 2. blog page(s), 3. guestbook and Control Panel (CP) areas- 4. update a blog page, 5. site update page) - See form on [login to view URL] for an example of how it's not working, [3] The CP log in doesn't seem to accept a username and password with cookie. At the moment it will only display /auto-log-in if a user's IP address is input into the configuration. This needs changing. [4] There are two 'Warning' errors when clicking the preview button on a form submission. This needs fixing. - View in Internet Explorer, fill form and click preview: [login to view URL] for example [5] Is there a way for pages without frames to acquire them automatically WITHOUT briefly showing [login to view URL] first? If so, implement the fix. - Notice how [login to view URL] loads Notes: * The back end uses a basic text file database not MySQL. * I can assist in all matters HTML and CSS, however I do not fully understand PHP or javascript. * You will be sent FTP details for a testing area on the site and payment made once the files in this area are fixed as per above description. * I've tried to be as detailed as possible but if anything needs clarifying, let me know.
