error mysqli.php on line 675

Fatal error: Class '' not found in //libraries/joomla/database/database/mysqli.php on line 675

The code:

protected function fetchObject($cursor = null, $class = 'stdClass')
{
return mysqli_fetch_object($cursor ? $cursor : $this->cursor, $class);
}

What does the error tells me? So I can look for a solution. After installing only sh404sef, and no other components or plugins.

More details here

sh404sef hein.... Remove it an I think you'll be just fine. By the way, there's no good SEF extension out there, those only generate problems or many you go after extras for certain Components, I've tried it all, extensively, and I've drop it all.

Best way to have SEF is to turn .htaccess and have a good, organized Main Menu that generates the links for you on J!1.7, rest is developers crap to sell.

hmm.. good bye my 39$? what doc. faq, etc, are u use for organized .htaccess ??

You can always ask a refund in a certain amount of time I presume.

I know this by experience, for instance, if you install Datso Gallery, url's in Joomla will display like this:

/component/datso/category3/item-36/photo-30

Example, only.

Ok, now, when you add Datso gallery to Main Menu as "Gallery", Joomla auto gerenates the SEF link as:

/gallery

And all those long-to-go/and-display/the-photo36

Turns into:

/gallery/view-photo/3/1

Or in a live example:

http://www.atmostfear-entertainment.com/v7/gallery/view-photo/3/1

Simple.

Also SEF Extensions generates logs and most mess up database, or conflicts with other components. sh404sef is well-known (not by newbies) for creating security holes, allow SQL Injections, and sometimes, even force the Administrator to reinstall everything again. Breaks layouts, tables, etc.

Major disadvantage is that any SEF Extensions generates multiple URL's, for instance, with K2 sometimes it generates 4 times more URL's than we need pointing to the same page or article, which over takes the site too much.

Be simple, the less Extensions you install in a Joomla site the better, and if you install Extensions which directly change's Joomla core of working, like SEF's, the more you rely on 3rd party developer to fix any issues you might have.

I'm here just giving you an advice.

it's cool! but hove in K2 change link from:

http://beta.***.co.ua/test/item/2-test-perevirka

to

http://beta.***.co.ua/test/test-perevirka

/test/ - category

/2-test-perevirka/ - article title

/item/ - some wtf!
