 * Hello,
 * After the last updates I’m getting an error message: 500 (Internal Server Error)
   
   Before update everything was fine.
 * [⌊error-message⌉⌊error-message⌉[
 * If I disable the “PDF for Contact Form 7” Plugin it works. I already reinstalled
   Contact Form 7 plugin and this one for PDF but it doesn’t helped.
 * I’m using PHP Version 7.1.11
 * How can I find where the problem exactly is?

 * I found the problem. There was a missing permission on the IIS Server.

 * hi [@safak93](https://wordpress.org/support/users/safak93/), may you share which
   permission in IIS server needs to be changed?
    We have the same problem but couldn’t
   find a solution. Many thanks.

 * found the solution –
    it’s due to memory_limit setting in your configuration.
   Was 128mb, and after set it to 512mb, all set.
