File Modifications Detected in Modules

[A. Mj]

Dear All

 

In my Prestashop Back office, i have figured a lot of file modifications detected in core and native modules.

 

And now i have no idea how to fix them. Since i have a very less knowledge on how to fix technical aspects such as these, i am yet to figure out how to fix them. Attached are the files showing which problems are arising in Core and Native modules & how page disappears in another attachment. 

 

With these file modifications, these re the following few problems i have founded. For example if some one is ordering on my website, after confirming an order at check out, page gets disappeared. Even if from the back office i am sending emails to that particular order, stating that your order has been processed or is in processing again screen disappears and no email message passes to the customer.

 

Please advice how to resolve this problem here ? I have no idea how to quickly fix this. Please help me out on this !!

I have no idea how to fix it. Please advice. All these are going above my head !!

I check now your site and its works.

[A. Mj]

Site is working. But if some one is ordering on site and checking out, after clicking "confirm order" page disappears.

 

When i click "Advance Parameters" > "Emails" from Back office, again page disappears.

When i also click "My Preferences" on the top right section of My Back Office, change my password, After clicking "Save" page disappears.

 

When some one places an order, and i try to send an email from my back office, neither i nor my customer gets any email. I have checked and tested with my another email as well.

 

I think any thing related to Emails, is not working, and page disappears. 

 

Please advice and HELP me out with this.

HOW TO ENABLE PRETASHOP DEBUG:

 

PrestaShop 1.5.3 -- 1.6

• open file: config/defines.inc.php  (using FTP or hosting control panel)
• change false-->true:

define('_PS_MODE_DEV_', false);

define('_PS_MODE_DEV_', true);

Now visit page(s) with issues and you should see underlying error message.

 

 

After doing that you supposed to see some error when usually you see blank page.

Fatal error: Call to undefined method Swift_Message::newInstance() in /home/redtagb1/public_html/classes/Mail.php on line 179

Check in modules list did you use some third party module that has used the old Swift Library directly.

[A. Mj]

how to check that now ?

[endriu107]

Check every module who can send email, you can turn it off and check pages if problem still exist.

 

You can also go to Advanced Parameters > Performance > Disable non PrestaShop modules switch to yes, and Disable all overrides switch to yes it show that the some module is a problem.

I went to Advanced Parameters > Performance > Disable non PrestaShop modules switch to yes, and Disable all overrides switch to yes it show that the some module is a problem but i am not figuring out how to find which one module is having a problem.
