 * I get an error in the error-log when requesting a page containing a Post list.
   The page contains this shortcode:
    [postlist id=755] The page is built correctly,
   but yet produces this error message:
 * [Mon Feb 10 09:16:29.692153 2020] [php7:warn] [pid 28635] [client ……] PHP Warning:

 * Please check if the shortcode have any html codes around the id. If using classic
   editor, use `Code Editor` mode (rather than `Visual Editor`) to check the shortcode
   you’ve placed.
 * Besides, i can see the shortcode is working on your site. Only issue i see is
   that the tag `<article>` needs a closing `</article>`.

 * Hi Shazzad,
    I always insert shortcodes in code mode, there is nothing surrounding
   the ID. I also placed quotes around the value, no luck. But it is working however….
   I also don’t see a button in tinymce to insert the code, I always do it manually!

 * Are you using this plugin version – 2.1.7 ?
    What is your server’s PHP version?
 * I couldn’t reproduce the warning yet.
 * Tinymce has retired.
