error itextsharp

Hi Guys can I help Me?

The problem occurs when I generate a PDF of an order request or when I generate an invoice, however both problems are solved if I replacing the dll no.web.dll the / bin folder of the same dll / bin folder.

Running the website on my server it works correctly already tried changing server exiting the business class for VPS however also not solved, the stranger and had times that the website was three days working properly on other occasions it worked correctly only one day.


The only thing I found is that the dll replacing nop.web.dll he returns to work.

the web site works perfectly on localhost and when Arvixe defective I just get the dll nop.web.dll and replace it with the same dll and the problem is solved.

observe that the problem is generated on the website:
as I said if I replace the dll site he returns to work. I believe that in order to solve this problem would have to know what happens in hosting the moment I replace the dll.

What made  you think to replacing nop.web.dll?   I would suspect that the replacement is just causing the web app to restart.  You could just "touch" the web.config to get same effect.

Hello New York! I thought about it so much that I tried to use the button located on the admin nop (alicativo restart) but it does not has the same effect, tried replacing another dll however without effect, I confess I have not tested with the web.config. but still do not know how to fix this flaw. day after day I have to replace this dll in order that the nop working again.

You have no idea what I can do in order to solve this problem?
