were introduced by many experienced magento developers and in this post we are going to share a couple of these which will be helpful for you in overcoming this situation. 

Solution 1: 

Here are some simple steps to follow up with:

2. Find the file name local.xml.sample and remove (.Sample ) from its name or simply rename it to Local.xml

Note: Doing step 2 might lead you to have loads of errors on your screen, which you should not be worry about. 

3. Now open file.php from magento/lib/Zend/Cache/Backend/File.php and search for:

protected $_options = array(

'cache_dir' => 'null',

Now replace it with 

Protected $_options = array(

'cache_dir' => 'tmp/',

4. Save the file. (overwrite, if you get the option) 

5. Create a temp folder in magento root domain folder

That’s it you are done, refresh the page and the errors will be gone!

Solution 2: 

Solution 2 is pretty much similar to solution 1 and it just goes up to 2 points of solution 1.

1. Open the errors folder from the root directory. 

2. Find the file named local.xml.sample and rename it with local.xml 

And refresh you page and the installation will move on without any Exception printing is disabled by default for security reasons.

And if you are curious to know about why all this happened then do see the errors log file.
