500 Server Error after upgrade

[alquds.eshop]

Hello,

I've upgraded my PrestaShop from 1.5 to 1.6.1.4 and I get "500 Server Error" when loading MyShop. I've already checked the error message by following "Benjamin Utterback"'s article and received this message.

"Current theme unavailable "default". Please check your theme directory name and permissions.

at line 259 in file classes/controller/FrontController.php"

and the line 259 in Red.

259.             throw new PrestaShopException((sprintf(Tools::displayError('Current theme unavailable "%s". Please check your theme directory name and permissions.'), basename(rtrim(_PS_THEME_DIR_, '/\\'))))); 

could Somebody help me, please?

 

Thank you so much.

So I tried to search in the InterWebz about this problem and it seems the problem is in the themes folder, I deleted the htaccess file but the problem still remains, 

I also tried to change the theme but have received this error message:"Duplicate entry '67-0-1' for key 'PRIMARY'".

INSERT INTO `ps_hook_module` (`id_module`, `id_shop`, `id_hook`, `position`)
									VALUES (67, 1, 0, 1)

It would seem you db for theme is not correct.

 

Here are screen shots of a non-multishop ps_shop and ps_theme tables, the ps_theme name must be located at themes/'theme name'.  for 1.6.1.4 it should be default-bootstrap.  If it just says default that would be from previous version.  Possible you can change ps_theme field name to fix.  Good luck.
