If you are loading PrestaShop 1.6 for the first time and you see only a blank white screen when you are trying to see the store. There is no error message and it will immediately appear as though your installation has failed. However, in most cases the problem is related to a memory setting in the PHP.INI file. You can easily edit your PHP.INI settings to allow for more memory and fix the problem. The following tutorial takes you through a few quick steps to edit the PHP.INI file or create a new one so that PrestaShop will load properly.

Editing the PHP.INI file to fix the PrestaShop 1.6 white screen

Note that this solution shows how to resolve the issue using the cPanel File Manager. If you require further information on using the cPanel File manager, please go to our documentation here. If you are not a Web Hosting Hub customer, then you can use an FTP client to download the file. You would then need to use a text editor to edit the file. Please follow the steps below in order to correct the white screen problem in PrestaShop 1.6:

  1. Login to your cPanel.
  2. Open the File Manager and select the Document root for the domain where you have loaded PrestaShop 1.6 or select Home Directory and locate the folder where you have installed PrestaShop 1.6.
  3. Locate the PHP.INI file. If you do not see one, then look in the PUBLIC_HTML folder for it, or simply create a new text file and name it "php.ini". Once you have located the file, click on the file and select EDIT. If you are creating the file, it will need to be saved in the same location as your PrestaShop installation files.
  4. When you edit the file look for the "Resource Limits" section or the "memory_limit" option. By default, the "memory_limit" is set to 32M. Change it to 256M in the editor as per the screenshot below. If you have created the PHP.INI file, then you will need to type in the following line: memory_limit = 256M;
  5. PHP.INI memory limit adjustment
  6. Click on Save changes.

Once the change has been applied, reload your PrestaShop site and you will see it function normally. If you require further assistance with the issue you're welcome to submit a question to our Community Support website, or contact our live techncial support team at any time.

Hello Jose,

We would need more information. What version are you using? Are you trying to create an account or checkout? If checking out, are you doing so logged in as a user or a guest? If a guest, is it trying to create an account or allow you to enter delivery information as you go? What do you see on the screen? Any error messages would be helpful.

Kindest Regards,
Scott M

Hello ali,

Thank you for your question. We are happy to help, but will need some additional information.

What were you working on when this started happening? For example, did you install a new Theme, or Addon before this started happening?

Also, what type of browser are you using? Such as FireFox, Chrome, or Safari, etc. Have you tried a different browser?

If you have any further questions, feel free to post them below.

Thank you,

Hello SAM,

Thank you for contacting us. I recommend enabling Error Reporting in PrestaShop, which should provide a more detailed message, instead of a blank page.

Please reply with any error messages you may receive so we can troubleshoot further.

Thank you,

Hello Darwin,

Thank you for your question. You will need to make this change in the php.ini file.

Please contact Live Tech Support, so they can copy the default server php.ini back to your account.

Then you can modify the php.ini file.

Thank you,

Hello Daisy,

Yes, when you create the php.ini file, it is blank. You may want to have our Live Support give you a copy of what is on the server. This has many settings already configured and you can change the settings from there.

Hello Katja,

I'm sorry to hear that your buttons are different colors in different browsers. Unfortunately, we are somewhat limited in this forum as far as offering any customized coding. However, if you're using legitimate HTML-acceptable colors you should be able to find a match that works for you.

Is there anything in the above article that you had trouble with specifically?
