500 Internal Server Error after install

[thesapper72]

Hi,

Getting a 500 internal server error after I have transferred files by FTP.  I try and go to my website so that I can then set Prestashop up, but am getting the error.

 

Thanks

500 errors are internal server errors. Ask your provider to read server log-errors and debug.

[vekia]

turn on error reporting, just follow this guide:
open config/defines.inc.php

 

find this line define('_PS_MODE_DEV_', false);

change to look like this: define('_PS_MODE_DEV_', true);

then instead of simple 500 internal server error you will see detailed information about issue (what and where doesnt work)

Hi, I am also getting the same error.

 

as suggested, made the changes to the file-

 

config/defines.inc.php:

 

('_PS_MODE_DEV_', false);

('_PS_MODE_DEV_', true);

 

- it still gives the same error. No changes at all.

 

Any other suggestions ?

Ask your provider to read the error-log-files of the server. Only with this files you can identify what is causing the problem.

 

Check also the min. server configuration for Prestashop:

• magic_quotes_gpc = off
• memory_limit = 128M min. (better 256M)
• max_execution_time = 300
• max_input_time = 300
• upload_max_filesize = 20M
• post_max_size = 20M
• max_input_vars = 5000
• allow_url_fopen = on
• safe_mode = off
• cURL - for Paypal and other services with API can to be work
• mod_rewrite = on

Getting Internal Server Error as well here:

 

http://www.drclark.it/store/modules/paypal/express_checkout/payment.php

 

getting:

 

PayPal response:
TIMESTAMP -> 2014-01-20T13:34:30Z
L_ERRORCODE0 -> 10002
L_SHORTMESSAGE0 -> Security error
L_LONGMESSAGE0 -> Security header is not valid
L_SEVERITYCODE0 -> Error

 

does the Paypal module need SSL?

No, but you have to configure Paypal correctly. Which Paypal module version are you using ? Did you created an API and added the details on module configuration ? Try to create a new API-Key at your Paypal account and change the details in your module settings.

Which Prestashopversion are you using ?

 

For PS 1.5. Paypal and 500 error there is a fix you can find here: http://nemops.com/debug-prestashop-error-500/#.Ut5B37QweUk

PS 1.5.6.1

 

Paypal Version 3.6.4

 

I looked at the fix and not seeing some of the files or even folders to find the files to edit.

You are not seeing Paypal module on your FTP /modules ? Also tried to create a new API and reconfigure your module on back-office ?

[mtporter]

Yes, I do see the PayPal module in FTP... but not seeing the 'same' folders/files they suggest to edit

 

What are the steps to generate a new API 

Edited January 21, 2014 by mtporter (see edit history)

[selectshop.at]

Perhaps the files are missing ? Download latest module and replace/acutalize your files. http://addons.prestashop.com/en/payments-gateways-prestashop-modules/1748-paypal.html

 

Steps for to generate a new API -> check on your Paypal-Account -> vendors tools.

[mtporter]

Downloaded. However, when you look at the URL in the fix of:

 

modules/paypal/views/templates/front/express_checkout/paypal.tpl

 

the folder /express_checkout is not on the store OR in the download (which would have included the file paypal.tpl).

 

Same for:

 

modules/paypal/views/templates/front/paypal.tpl

 

the file paypal.tpl is not on store OR in the download

 

And last the fix URL of:

 

modules/paypal/express_checkout/paypal_express_checkout.php

 

the file 'paypal_express_checkout.php' is not on store OR in the download

[selectshop.at]

Yes indeed seems that agin something was changed in Paypal-Module. Please try to generate a new API and configure them on back-office-module settings.

 

The error is related to an insecure key, or invalid old key.

Your server has cURL installed and activated ?

See official API error-codes here: https://developer.paypal.com/docs/classic/api/errorcodes/

There you also can read tutorial on how to create or validate your API.
