Hi,

I don't know if this as been talked befored,

In Nopcommerce 1.90 while trying to export customer invoice to pdf, nothing happens, but on the error log, it shows this:

? Log type:   CustomerError

Any idea?

Ensure that you run nopCommerce in medium trust (required for PDF)

Thanks very much Andrei for the reply!

"Close but no cigar" heheh!

I asked the company where I have my website hosted, they say that they have a customized "trust", in other words, between medium and full trust.

Unfortunately I can't export pdf in medium trust, they momentarily changed to full trust and it worked, but they say it's not secure as it is an shared host.

I saw this topic:
https://www.nopcommerce.com/boards/t/3087/creating-a-pdf-invoice-in-medium-trust-environments-a-solution.aspx?p=1

It seems there is a proposed solution, but does it really works?


Any help would be grateful!

(I have installed NOPCOMMERCE 1.9 version)

That solution is outdated. The solution is to run nopCommerce in full trust

Thanks very much for the reply Andrei!



Wow! I'm confused, is it "medium trust" or "full trust" (for pdf exporting) ?

I used the solution provided on that link, but didn't solve the problem.



I'm not sure but I edited web.config file and inserted :
<system.web>
      <trust level="Full"/>
      . . ..


And it works, I'm not sure if my host provider has the possibility of "full trust", but denies it. The truth is that after inserting that line, it is working.

Manuel,

It's "full trust". It doesn't work in medium trust

Thanks Andrei!

Another aspect that I saw, my online shop seems faster after the change, what should be the reason?

No, trust level doesn't affect performance
