PrestaShop Tips - set display_errors to on for trouble shooting

I experienced an issue when I switched my hosting server. I took me a lot of time to find out the cause and fixed the problem. Here I put this tips as memo, hope it will help myself to remember and also share the tips with any one experience the same problem.

The symtom my issue is:
When login to back office at PrestaShop and tried to config my moules at modules tab, but the page is empty, no modules is displayed. No error is displayed.

I checked everything as instructed in the PrestaShop Wiki, such as folder permission, modules class files and so on, but I was still not luck.

Finally, I found there is configuration item "display_errors" in config file.
By default it is set as 'off' as indicated below.

@ini_set('display_errors', 'off');

I changed this config item value from 'off' to 'on' than re-run my page, the following error was displayed.


Fatal error: Class 'ModuleGraphEngine' not found in /hsphere/local/home/c270727/carnvee.com/classes/Module.php(323) : eval()'d code on line 13

Then I checked file ModuleGraphEngine.php under classes folder and found the file size was zero (0). I am pretty sure at this momemnt that the cause of problem is the stupid file transfering issue.

PrestaShop Tips - How to setup favicon

What is a favicon?

A favicon (short for favorites icon), also known as a website icon, shortcut icon, url icon, or bookmark icon is a 16×16, 32×32 or 64×64 pixel square icon associated with a particular website or webpage.

A web designer can create such an icon and install it into a website (or webpage) by several means, and most graphical web browsers will then make use of it. Browsers that provide favicon support typically display a page's favicon in the browser's address bar and next to the page's name in a list of bookmarks. Browsers that support a tabbed document interface typically show a page's favicon next to the page's title on the tab. Some programs allow the user to select an icon of his own from the hard drive and associate it with a website.

How to setup

Here is the instruction to setup a favicon for your PrestaShop.

Create a favicon use any tools you have like PhotoShop.

You can use some free online tools or service like http://www.favicongenerator.com/.

PrestaShop Tips - Customiize Paypal payment page to use your own logo and image without https

If you are running eCommerce shopping cart or online shop software like PrestaShop and you are using Paypal, but you don't have HTTPs, in that case you will not able to customize Paypal payment page to use your header image or logo.

But I found a very tricky way to do customize Paypal payment to use your own logo or header image. Here is how to do:

[Prepare your logo and get an URL with https]
First, you will have to get your logo or page header image done. Then upload your image to any website with HTTPS (SSL) enabled that you have access. And get the URL of your logo or header image.

If you don't have any website to upload, you create an account at Microsoft Windows Live account, then create a Shared Album at Windows Live Photos, and upload your image there and share your image with public. So you will get an URL of your image.

Note: By default, the URL might be non https, but it works with https too.

[At your Paypal Account]
1.From the Account Overview page, click on the Profile sub-tab

2.Click on the Custom Payment Pages link under the Selling Preferences heading.
This will take you to the Custom Payment Page Styles page.

3.From this page, you can Add, Edit, Preview, and Remove page styles,
as well as make any page style your Primary style

[At your PrestaShop]
4 If your image URL is a Shared image from WIndows Live Photos , then the URL might be too long to fit in your Paypal setting page.(It does not allow very long image URL). In that case, you can have it set up at your PrestaShop Paypal module screen.

You can see the sample by going yo paypal payment page at:
