Hi there,
this is a z-index CSS issue. You should edit the Easy Bootstrap Shortcodes css located at plugins/easy-bootstrap-shortcodes/styles/bootstrap_admin.min.css (starting at line 309).
From:
body.ebsp-mf-shown .mfp-bg { z-index: 10000 !important; }
body.ebsp-mf-shown .mfp-wrap { z-index: 10001 !important; }
body.ebsp-mf-shown .mfp-preloader { z-index: 10002 !important; }
body.ebsp-mf-shown .mfp-content { z-index: 10003 !important; }
body.ebsp-mf-shown button.mfp-close,
body.ebsp-mf-shown button.mfp-arrow { z-index: 10004 !important; }
to
body.ebsp-mf-shown .mfp-bg { z-index: 100000 !important; }
body.ebsp-mf-shown .mfp-wrap { z-index: 100001 !important; }
body.ebsp-mf-shown .mfp-preloader { z-index: 10002 !important; }
body.ebsp-mf-shown .mfp-content { z-index: 100003 !important; }
body.ebsp-mf-shown button.mfp-close,
body.ebsp-mf-shown button.mfp-arrow { z-index: 100004 !important; }
Unfortunately we cannoth change our z-index in order to prevent breaking compatibility with other plugins, so I’ll ask the Easy Bootstrap Shortcodes devs to apply the above change on their plugin.
