gdoc query shortcode causes ‘invalid JSON response’ error when saving

    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?
