error 500 when i reply to customers

[msimballaggi]

hello everybody, i am new on prestashop and i am trying to configure my website contact form, when i send a form as a customer to my website as test, it works, but when i try to reply through my backoffice, it gives me this error, can somebody explain me why?

Have you tried turning debug mode on ?

 

Do you have access to server logs? Could also look for some information from there.

What PrestaShop version and what PHP version are you using?

[msimballaggi]

prestashop 1.7.5.2 and php 7.3.5

[Kert L]

PrestaShop does not support PHP 7.3 unfortunately, change it to 7.2 and you should be good.

now i changed it to the 7.2.18 but it still givee me that error

edit: and even with the 7.0 it still doesn't work

Verify that it is 7.0 or 7.2. You can go to Advanced parameters - Information

Turn on debug mode, this can also help to identify the problem. 

[msimballaggi]

as you can see

[Kert L]

Try turning on the debug mode. If it still shows you 500 Error page, you have to look for server errors ( error_log )

If it displays some error and you do not understand what it means then Copy or take a picture of that error and show us.

Look at this post:

 

Turn on debug mode, then try to reply customer again. 

[msimballaggi]

Fast reply: Delete the picture or blur it, since it contains some user information and your shop address

[msimballaggi]

picture deleted

[Kert L]

For reference the problem is in this function "idn_to_ascii" In Mail class method toPunycode ( classes/Mail.php:893 )

 

From php.net idn_to_ascii requires intl >= 1.0.2

You can verify if you have these requirements from phpinfo

<?php

phpinfo();

added intl image from phpinfo (see edit history)

[msimballaggi]

in which file?

[Kert L]

You can create a info.php file in your web folder , copy paste the code i gave you and access it through URL yourshop.com/info.php

Make sure to delete the file after you are done with it

[msimballaggi]

i don't have the internazionalization support in the file

[Kert L]

You could ask your hosting if they could enable it or look php modules/settings in your control panel
