Okay, I will try.
I took a j2.5 website and updated that to the latest j3 version. Then I installed the mo template.
It works okay and I am changing the module position names etc.; generally changing small things everywhere to get the site and the template matched.
That was last week and yesterday.
All works well.
Todat I installed the contact plugin, from the package of files inside the zip file called gk_mo_rest_files_K!3.
I went to upload the newspro module, made a new newspro module saved some settings, and lost the site.
Or so it seemed. I called your help, and went looking via the file browser in my cpanel.
Saw your response, checked the contact plugin files and saw that captcha was enabled (1 settings).
I renamed the corresponding php file: plg_gkcontact.php to deactivate te file, got the site back, and checked the setings for the plugin in the plugin manager: see image attached.

I changed the use recapcha setting to no, saved the new settings, restored the correct name for the plg_gkcontact.php file and kept the site intact.
So: perhaps in the rest file the setting for recapcha is set to yes, where it should be set to no?
Greetings,
