Magento 1.7 cannot edit some products - php

Question

I am on Magento ver. 1.7.0.0 and I can't edit some of the products from the admin backend.
When I tried to change the product description directly using mysql it worked, so then I tried removing parts of the description and then found that
everything till the text 'printer driver lets users transfer data' works but when I added the word 'from' to it ,it didn't work making the paragraph end in 'printer driver lets users transfer data from' did nothing ,neither showed a error nor a successful message it just refreshed the page. It can't be about the length because if I replace the text from to krom it works.
So I tried editing the description to just 'printer driver lets users transfer data from' it worked
From the system.log:
ERR (3): Warning: array_key_exists() expects parameter 2 to be array, null given in //app/code/core/Mage/Adminhtml/controllers/Catalog/ProductController.php on line 507
ERR (3): Recoverable >>ERRor: Argument 1 passed to Varien_Object::addData() must be an array, null given, called in //app/code/core/Mage/Adminhtml/controllers/Catalog/ProductController.php on line 514 and defined in //lib/Varien/Object.php on line 243
ERR (3): Warning: Invalid argument supplied for foreach() in //lib/Varien/Object.php on line 245
The Chrome console tells me :
index.php/admin/catalog_product/validate/id/1/back/edi…roduct_info_tabs_group_7/key/978d8fe4570a41312a7520945e982662/?isAjax=true 500 (Internal Server Error) prototype.js:1530

onclick
A little PHP debugging tells me that for the product with description error
$product->getAttributes(); was empty but for the working products it was an array.
$attributes = $product->getAttributes();
around line 504 of app\code\core\Mage\Adminhtml\controllers\Catalog\ProductController.php
If I change the following part from the form.js there is no Chrome console error but it still doesn't work:
this.submitUrl = url;
if(this.validator && this.validator.validate()){
if(this.validationUrl){
this._validate();
}
else{
this._submit(); // I removed everything but this
}
return true;
}
If it helps there are 5881 characters before the word 'from' in the description.
I have tried editing in all major browser so there are no compatibility issues.
I believe the problem is somewhere in the javascript but can't find where. Even if I can just remove the validation script from the admin forms I will but I don't think I should and I don't know how.
Any help would be greatly appreciated.
Thanks for your time.

Take a closer look at your .htaccess file. When I migrated my 1.7.0 Magento store to another server I included the .htaccess file from the old server and then the message: "Invalid Form Key. Please refresh the page" popped on screen and nothing happened, not even the configuration changes had effect.
The solution was to install a fresh Magento and then copy the My Store files the the Magento root, excluding .htaccess. When I used the .htaccess from the fresh installation, everything started to work fine. I don't know what exactly happened, maybe each server structure has different and particular .htaccess entries and rules. It works to me.
