Error 500 when adding product to cart or new customer

[Igbarah]

Hi, I have migrated a Prestashop 1.7.5.2 store from one server to another and when a new user registers it gives an error, the same thing happens when buying a product, it makes a kind of infinite loop and does not allow to buy anything.

I have tried changing the PHP version from 7.3 to 7.0, 5.4 without success. I have tried changing the template for the default one and the same problem. I think it is something of a module, but I have deactivated many of them and it continues with the same error, the truth is I am desperate, I have tried to "crush" the whole store for a new one of the same version but I get an installer and in the database breaks saying table already exists.

I have disabled the cache, I have also set debug mode, and Disable PrestaShop non-native modules to YES, and Disable all overrides methods. Yes, now it gives me an error when clicking "Add to cart".

You can  delete cache for cache folder via ftp. Inside car/cache 

1. Disable no seo url from seo area and enable seo mode.

2.  Force compile in backend 

3. Clear server cache 

4.  Test non seo url mode.

5. Test with default PrestaShop theme 

 

I think with the above trips you are able to solve 

Thank you

Also try with reset cart module. Clear cache after.

Thanks very much ComGrafPL, I try to reset the ps_shoppingcart module but don't show the buttons reset or disable, I rename it and re-upload but the same problem.

First of all: did you clear the cache after each change of PHP version?

The error appears on line 481 of CartPresenter.php. Have a look at that line and try to find out with debug code what the problem could be.

Hi musicmaster, yes I clear the caches after the changes. I can't find the file CartPresenter.php, but I try to replace the module ps_shoppingcart inside the theme warehouse and crash all the web whit error 500, when restore the ps_shoppingcart the shop work again.
