rocky Posted January 15, 2011 Share Posted January 15, 2011 What's the entire fatal error message? Link to comment Share on other sites More sharing options...
albsim81 Posted January 15, 2011 Author Share Posted January 15, 2011 What's the entire fatal error message? Only fatal error. No other word Link to comment Share on other sites More sharing options...
rocky Posted January 15, 2011 Share Posted January 15, 2011 That's not enough information to help. Try uncommenting the debug_backtrace line in the displayError function of classes/Tools.php. That should give you a stack trace with more information about the error. Link to comment Share on other sites More sharing options...
soorovi Posted January 24, 2011 Share Posted January 24, 2011 That's not enough information to help. Try uncommenting the debug_backtrace line in the displayError function of classes/Tools.php. That should give you a stack trace with more information about the error. what should i do with that stack trace? for example i have 7 objects in that array. where can i find the one that initiates the FATAL ERROR message?and what information is useful in the following lines? [0] => Array ( [file] => /var/home/public_html/classes/Product.php [line] => 1432 [function] => displayError [class] => Tools [type] => :: [args] => Array ( ) ) Link to comment Share on other sites More sharing options...
rocky Posted January 25, 2011 Share Posted January 25, 2011 That tells you that it is line 1432 of classes/Product.php that is throwing an error, which is the following: if (!Validate::isBool($usetax) OR !Validate::isUnsignedId($id_product)) die(Tools::displayError()); So it seems either $usetax is not either 0 or 1, or the $id_product is not valid. I think the latter is more likely. Make sure there are no $id_product with value 0 in your database. You can use the rest of the stack trace to figure out where it is.

soorovi Posted January 31, 2011 Share Posted January 31, 2011 no, there are no zero values in product id's also there are no zero-value tax id's.actually this Fatal error appeared right after the initial shop installation. i am confused and do not know what to do.

dustybrown Posted February 1, 2011 Share Posted February 1, 2011 I have the same problem. PrestaShop shows FATAL ERROR and nothing else at all, and the admin page shows nothing at all. I am using StartLogic and I did all of the write permissions, the GDLibrary change, etc. I am at a loss. Link to comment Share on other sites More sharing options...
