Clean Cache and Session in Magento

If you have made any modifications to your Magento code, they will not appear immediately unless you clear the cache.

Magento keeps its cache in /var/cache located inside the Magento home directory. So, for example, if your Magento is installed in your main www/magento folder, the cache will be in magento/var/cache.

To clear the cache, simply delete everything from the /var/cache directory and then reload your website in your browser.

To clear all sessions, you can also delete everything from the /var/session folder within your Magento home directory.

Solution of Unable to communicate with the PayPal gateway in magento 1.7

I am using magento 1.7.0.0 version and it is quite advance then older version. When i have integrated Express Checkout in my localhost magento admin as it is quite simple, you can get many tutorials for it. But the main problem come in front of me when i placed an order using Paypal Express Checkout., it display an error msg "Unable to communicate with the PayPal gateway" ..

Solution : The fix for me was to disable SSL verification at configuration >> system >> payment methods >> PayPal payment solutions >> Enable SSL verification . If you were testing on the localhost as well, re-enable the option on your live site to check whether it works. Otherwise just disable it until a proper fix has been found for magento 1.7 +

I think it may help you !!!!

Hi All,

I have done a lot of R&D to find the solution of Google Custom Search White Space Issue.

1. <form action="http://www.test.newhomestar.com/search.php" id="cse-search-box">
<input type="hidden" name="cx" value="xxxxx90948434568903:14dqcrlsktw" />
<input type="hidden" name="cof" value="FORID:11" />
<input type="hidden" name="ie" value="UTF-8" />
<input type="text" name="q" size="31" class="inp-hdr"/>
<input type="submit" name="sa" value="" class="go-button" />
</form>
<script type="text/javascript" src="http://www.google.com/cse/brand?form=cse-search-box&lang=en"></script>

//Create a div and do inline styling and put height:1140px or as per your requirement.

2. <div id="cse-search-results" style="overflow: hidden;text-align: left; height:1140px"></div>
<script type="text/javascript">
var googleSearchIframeName = "cse-search-results";
var googleSearchFormName = "cse-search-box";
var googleSearchFrameWidth = 590; <!----you can change width
var googleSearchDomain = "www.google.com";
var googleSearchPath = "/cse";
var googleSearchResizeIframe = true;
var a=encodeURIComponent;
</script>
