 * Hi,
 * first of all, I’ll quickly state my specs. My site is running on:
    – PHP 7.2.29(
   Apache) – WordPress 5.3.2 – the following plugins: Contact Form 7, Events Made
   Easy, NextGEN gallery, ShortPixel image optimizer, W3 Total Cache, WP-Optimize
   and Yoast SEO.. and Inline Google Spreadsheet viewer of course.
 * I am an administrator of the website and I’ve enabled the possibility to SQL 
   query in the settings. However, when I want to insert the [gdoc] shortcode in
   a normal page, things go awry.
    – All goes well when only using [gdoc] shortcode
   itself – The moment I want to query with either [gdoc key=”wordpress”] or [gdoc
   key=”mysql: etc”] and I want to save the page, a red alert appears, saying: ‘
   The response is not a valid JSON response’.
 * Checking the POST call WordPress makes when clicking the save button and it returns
   the following error:
    ‘<h1>Error thrown</h1><p>Call to a member function has_cap()
   on boolean</p>’
 * I’m out of ideas. Can anyone help me?
