 * Hi [@lewiswordpress](https://wordpress.org/support/users/lewiswordpress/)
 * We will look into it and let you know.
 * One more thing – could you copy and paste error log (related to ShopMagic) from
   WooCommerce > Logs (unless it’s the same as above)?

 * [@damianmachnik](https://wordpress.org/support/users/damianmachnik/) While I 
   know you have the best of intentions, it’s forum policy that you _not_ ask users
   for admin or server access. Users on the forums aren’t your customers, they’re
   your open source collaborators, and requesting that kind of access can put you
   and them at high risk.
 * If they _are_ paying customers (such as people who bought a premium service/product
   from you) then by all means, direct them to your official customer support system.
   But in all other cases, you need to help them here on the forums.
 * Thankfully are other ways to get information you need:
    - Ask the user to install the [Health Check plugin](https://wordpress.org/support/plugin/health-check/)
      and get the data that way.
    - Ask for a link to the [http://pastebin.com/](http://pastebin.com/) or [https://gist.github.com](https://gist.github.com)
      log of the user’s web server error log.
    - Ask the user to create and post a link to their `phpinfo();` output.
    - Walk the user through [enabling WP_DEBUG and how to log that output to a file and how to share that file.](https://wordpress.org/support/article/debugging-in-wordpress/)
    - Walk the user through basic troubleshooting steps such and disabling all other
      plugins, clear their cache and cookies and try again (the Health Check plugin
      can do this without impacting any site vistors).
    - Ask the user for the step-by-step directions on how they can reproduce the
      problem.
 * You get the idea.
 * We know volunteer support is not easy, and this guideline can feel needlessly
   restrictive. It’s actually there to protect you as much as end users. Should 
   their site be hacked or have any issues after you accessed it, you could be held
   legally liable for damages. In addition, it’s difficult for end users to know
   the difference between helpful developers and people with malicious intentions.
   Because of that, we rely on plugin developers and long-standing volunteers (like
   you) to help us and uphold this particular guideline.
 * When you help users _here_ and in public, you also help the next person with 
   the same problem. They’ll be able to read the debugging and solution and educate
   themselves.

 * Hi [@sterndata](https://wordpress.org/support/users/sterndata/) Understood. As
   you noticed, no harm intentions on our side. We just want to check (and fix) 
   this issue as soon as possible.
 * Helping users through WP forum is crucial, however sometimes the only solution
   for a possible bug is fixing it on a developers’ side. We believe that this may
   be such a case.
 * [@lewiswordpress](https://wordpress.org/support/users/lewiswordpress/) As we 
   are not able to recreate this issue on our end (ShopMagic works fine with Contact
   Form 7), could you take a look at what Steven wrote? We’ll start with:
 * – Link to the [http://pastebin.com/](http://pastebin.com/) or [https://gist.github.com](https://gist.github.com)
   log of the user’s web server error log.

 * Under NO CIRCUMSTANCES may you ask for a login to a user’s site on these forums.
   That’s a hard NO and NEVER.

 * Hi [@lewiswordpress](https://wordpress.org/support/users/lewiswordpress/)
 * We haven’t heard from you for almost three weeks, so I’m going to go ahead and
   close this ticket for now. However, if you’d still need our help or if you have
   any other questions, please feel welcome to share those here. We’d be happy to
   assist.
