Troubleshooting

Turning the error message display on in case of un= expected and persistent blank pages

Module

If your back office and/or front office start displaying a blank or inco= mplete page regularly without any error message, it is necessary to activat= e the display of the PHP errors in order to understand the problem.

This is done in your PrestaShop installation's /config/defines.inc= .php file. You should edit the following line:

=20
define('=
_PS_MODE_DEV_', false);
=20

...and change it into:

=20
define('=
_PS_MODE_DEV_', true);
=20

Now browse your store's pages again. PrestaShop will display all the rel= evant error messages (if any), which should help you solve the issue.

Once the issue has been fixed, you must revert your changes: edit the /config/defines.inc.php file again and put false back as the val= ue for the _PS_MODE_DEV_ constant.

= Hosted at 1&1: Solving the memory allocation issue

Some people may encounter memory allocation issues, particularly when th= e back office tries to display images which are quite big in the disk (over= 800 Kb). You should know that even if you manually increase the hosting me= mory limit to 128 Mb, some web hosts, such as 1&1, will keep the limit = at 32 Mb. See this FAQ from 1&1: http://faq.= oneandone.co.uk/scripting/php/10.html.

There are only two solutions, and they are both drastic:

It is impossible = to connect anymore

There are cases when PrestaShop will not recognize a user's e-mail or pa= ssword, making it impossible to connect to either the back office and the f= ront office. The user is simply sent back to the login screen. Some reports= tend to point that IE10 is the only browser where this happens.

This is most probably an issue with the user's browser cookie for your s= tore: when the user repeatedly logs in and out of the store, the cookie's e= ncryption keys can get mixed up.

In any case, one easy way to fix this and to be able to log in again is = to clear the browser's cache and cookies. Here is page explaining how to do= just that, depending on the browser: https:= //support.google.com/mail/answer/32050?hl=3Den.

Regenerating a pas= sword manually

There are situations where nothing happens when you request a new passwo= rd, and it doesn't work. There can be a number of reasons why this would ha= ppen, but the important thing is to be able to log in again.

This is will require you to access your database, using phpMyAdmin for i= nstance.

You will have to follow the following procedure:

  1. Open the /config/settings.inc.php file, from your shop's r= oot directory. Find the line containing "_COOKIE_KEY_". Copy t= he cookie content (without the quotes): it is the MD5 for your original pas= sword.
  2. You now need to generate a new MD5 hash for your password:
    1. Go to http://www.miraclesalad.com/webtools/md5.p= hp.
    2. Paste the value of "_COOKIE_KEY_" in the text-field, = and right after it, add your desired password. For instance, xykxB41JrEacRI= oZxDioPNRmKeuO3ixCLygNxBAkeOkAHf2YUVESuT9jMYPASSWORD, where the cookie ends= with T9j, and the desired password is MYPASSWORD (it can be anything you w= ant).
    3. Click on the "md5" button: this will produce a MD5 hash of the text-fie= ld's content. Copy it.
  3. You now need to put this hash into your database:
    1. Open you shop's database using phpMyAdmin. If you don't know how to use= phpMyAdmin, ask your webmaster, or your host.
    2. Open the pw_employee table, find the row corresponding to = your account (it should feature your first name, last name, and e-mail addr= ess), and click its "Edit" button.
    3. Find the passwd field, and paste in the MD5 that you just = generated.
  4. Log in to your back office with the email listed in the same table, and= the desired password that you used above (MYPASSWORD). This will generate = a new cookie key.

If it still doesn't work, use phpMyAdmin to access the ps_shop_url= table and check the value of the main shop, whose id i= s 1. It should contain the shop's file path:

If all fails, contact the PrestaShop support team at http://= support.prestashop.com/en/.

PrestaShop = does not send me my new password

The request to reset the password only works if the SMTP server has been= configured so that PrestaShop is able to send emails.

Two solutions present themselves to you:

  1. Configure the SMTP server to send emails:
    1. Get information for SMTP connection from your hosting provider.
    2. Go to your back office (either you or an administrator who can still lo= g) "E-Mails" page, in the "Advanced parameters" menu.
    3. Select the "Use my own SMTP settings" option. A form will appear: fill = it with the information given by your host.
    4. Save your changes.
    5. Request a new password once again. You should receive it.
  2. Follow these steps:
    1. Choose a new password. In our example, "$$$rabbit$159$$$".
    2. Using your FTP client, open the login.php file, located in= your administration folder online (the name of which depends on your insta= llation).
      At the bottom of the file, add the following line:
      = echo md5( PSQL( _COOKIE_KEY_ . 'newpassword' ) );
      So with our ex= ample password:
      echo md5( PSQL( _COOKIE_KEY_ . '$$$rabbit$159$$$'= ) );
      Remember to put your own new password!
  3. Go to the login screen to the back office, as if you wanted to log in, = and copy the text that appears at the bottom of the page (e.g.: a0ee884b507= dd4624ce51968cfbb19a9).
  4. Go to the PrestaShop database, for example using phpMyAdmin. In the ps_employee table, replace the existing value in the passwd= column for the employee of which you want to change the password wi= th the value obtained in the previous step. Save your changes.
  5. You can now connect with the usual username and new password.

Logging in after mistakenly deleting the default language pack

In the event that you deleted the default language pack from your shop i= nstall, you can have issues connecting to your back office again.

Here how to solve this if the default language was English:

  1. Go to phpMyAdmin. If you cannot access it, ask your host to perform the= se actions.
  2. Select your shop's database, and select the ps_lang table.=
  3. Click the "Insert" button at the top, and create a new entry with these= values:
    • id_lang -> 1
    • name -> English
    • active -> 1
    • iso_code -> en
    • language_code -> en
    • date_format_lite -> Y-m-d
    • date_format_full -> Y-m-d H:i:s
    • is_rtl -> 0
  4. Execute the query.

You should be able to log in again.
