Fixing Sharepoint lightbox in multiple lines with rich text enhanced columns when ShortPoint installed.

Issue

1.  When creating or modifying a SharePoint list, create a multiline text column and turn on “Use enhanced rich text.

2.  Try to edit the multiline text for one list item and click Embed code,
The expected behavior is that a lightbox should appear.

3.  If nothing happened or the lightbox displayed in a malformed appearance you can fix it with the following workaround.

Workaround

1.  Copy the following: spdisable=1


2. In the address bar delete everything after “.aspx?” from the URL and then paste spdisable=1 right after the question mark

3.  Hit enter to reload the page.

4.  Now the lightbox should behave as expected.
