Joomla! is failing me.

[CaldwellYSR]

So I've run into a problem with Joomla! I've posted on the joomla forums but nobody seems to answer me and I've gotten good responses from here before so hopefully someone can help me.

The problem is when I go to add any new content to the back-end of my joomla site, I can't do it. At the top of the page I'm getting three warnings that look like:

Warning: Invalid argument supplied for foreach() in /Applications/XAMPP/xamppfiles/htdocs/libraries/joomla/database/database/mysqli.php on line 727

Warning: Invalid argument supplied for foreach() in /Applications/XAMPP/xamppfiles/htdocs/libraries/joomla/database/database/mysqli.php on line 727

Warning: Invalid argument supplied for foreach() in /Applications/XAMPP/xamppfiles/htdocs/libraries/joomla/database/database/mysqli.php on line 727

So if I go to line 727 of the file it's giving me it says:

/**
	 * Retrieves information about the given tables
	 *
	 * @param	array|string	A table name or a list of table names
	 * @param	boolean			Only return field types, default true
	 * @return	array	An array of fields by table
	 */
	public function getTableFields($tables, $typeonly = true)
	{
		settype($tables, 'array'); //force to array
		$result = array();

		foreach ($tables as $tblval) {
			$this->setQuery('SHOW FIELDS FROM ' . $tblval);
			$fields = $this->loadObjectList();

			if ($typeonly) {
				foreach ($fields as $field) {
					$result[$tblval][$field->Field] = preg_replace("/[(0-9)]/",'', $field->Type);
				}
			} else {
				foreach ($fields as $field) {
					$result[$tblval][$field->Field] = $field;
				}
			}
		}

		return $result;
	}

I don't know enough php to completely understand this but it's the last foreach that is causing the problems. I THINK it has to do with getting the values from the boxes where I type in the article title and whatnot. I'm probably wrong though...

and then if I try to fill out the new article and save it despite the warnings it says:

Save failed with the following error: Please provide a valid, non-blank title.

This is the second time I've had this problem. The first time it happened I googled and googled to find the answer and for the first time in a long time google failed me. So I did a fresh install of xampp and joomla! and made the sit again and now the same problem has come up. This is my first site building my own theme instead of just using the themes given to me by default. It's getting quite frustrating to tell my friend that her site is ready to go just to tell her it's broken again. I'm doing all of this locally on my computer for now, I was planning on putting the site online when we got everything finalized. Any help fixing this would be appreciated so that I can get my first real website online.

Hmm, never seen that one before. Did you successfully create any articles before you started seeing the problem?

It might be worth trying it on the web server, it'll probably be more robust than developing locally.

Try what Pheno said. I've always had issues with local installs.

Yes I got some articles in. As a matter of fact I was able to put anything I wanted in to start. It problem came up when I finished with all the info that I currently had and closed the site. When I came back the next day to add the extra information that I had gotten I had that error. I'll try putting it online and see how that goes.

Do you know of any decent free hosting servers that support joomla 1.6? The site is a small portfolio for a writer/photographer friend of mine and it's really not worth paying for hosting... It's more of an expirement for both of us.
