500 Internal Server Error between Cart and PayPal

[IrishGuy]

I am receiving 500 errors since yesterday. It happens before reaching the PayPal page, I've called PayPal and they say that it is not reaching them at all. I have called my hosting company and they say it is some coding issue as their server is working. I haven't changed any code and it was working 2 days ago.

Here is the customer error:

----

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at [email protected] to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

I received error report below be email, I deleted the params sent as it contains user information but they look standard. Anyone have any ideas?

Error reporting from your PayPalAPI module   A client has encountered a problem with the module PayPalAPI, see the report:  

PayPal response:
-> 
Making new connection to 'api-3t.paypal.com/nvp'
Connect with CURL method successful
Sending this params:

 

 

// I have deleted the params sent

 

 

Send with CURL method failed ! Error: Resolving timed out after 30000 milliseconds

Connect failed with fsockopen method 

 

----

 

I am using PayPay module v3.10.2


Please help, this is my only payment method so my site is essentially redundant at the moment.

This seemed to 'resolve itself' after about 36 hours after this post but it has happened again now. I am on a shared hosting platform but the hosting company say that it is nothing to do with them as do PayPal. 

 

Does anyone have any ideas? Or even how I could try and debug it? 

I'm pretty new to prestashop. 

 

Thanks

Did you activate dev mode while getting the error?

[IrishGuy]

I didn't do that.

 

I just do the following?

 

go to config > defines.inc.php change the line:

define('_PS_MODE_DEV_', false);

to true and you're done

 

And then where do the errors show?

[IrishGuy]

Also just found these errors on the configuration page:

 

Required parameters: Please fix the following error(s)

• Some PrestaShop files are missing from your server.
  (/localization/fr.xml)

Optional parameters: Please fix the following error(s)

• Allow the PHP fopen() function on your server.

 

Reading this post: https://www.prestashop.com/forums/topic/124749-solved-problem-with-fopen/ it looks like it is not best practice to turn this on.

 

Also, I have been receiving orders without a problem at other times so I'm not sure why this has now happened twice that people can't get to the paypal page.

OK. Now all of a sudden it has started working again. I have no idea what is causing these sporadic issues.
