Fatal Error Block::getInstance

Fatal error: Block::getInstance() [<a href='block.getinstance'>block.getinstance</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition &quot;HtmlAudioBlockController&quot; of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /home7/thealcke/public_html/concrete/models/block.php on line 328

^^^^ This appeared when I uninstalled an add-on and now I am unable to access the website/login. Please, help!

Bump!

I'm running into the same issue while trying to develop a custom package for sermon uploads. I've uninstalled/reinstalled the package several times and still get: 

Fatal error: Block::getInstance() [<a href='block.getinstance'>block.getinstance</a>]: The script tried to execute a method or access a property of an incomplete object.

This is without me even having started working on the front end block. Right now, I've just been developing the admin interface...

Hi i had same problem.
Solution is that just uninstal your theme one time and activate another theme and after that you have activate your theme.
Then you got the solution

I had this same type of hiccup after I purchased a gallery addon. The reset your site trick worked for me as well.

I had the same problem, and found a workaround, so this might help someone else.

It seems to be related to the cache feature. By simply running the upgrade script, it will clear the cache. Here's instructions on how to run the upgrade script:

Go tohttp://www.yoursite.com/index.php/tools/required/upgrade... (Note: if this does not work, tryhttp://www.yoursite.com/index.php/tools/required/upgrade.php)...

Hope this helps someone.

And if any developers are looking for a permanent fix, I found one.

Add the following to your package's controller.php file:
public function uninstall(){
   Cache::flush(); //remove items from cache
   return parent::uninstall(); 
}


This will automatically run when the package is uninstalled and clears the C5 cache just beforehand. So there's no more nasty error.

Thank you! Adding the uninstall function solved the problem.
