 * Please help.
 * Tablepress was behaving unusually, a section of rows at the bottom had a red 
   color over them, and they stopped showing on the page.
 * I saw there was an update available and thought that might help, but not I have
   a worse problem, the rows are still missing and I now have the following error:
 * DataTables warning: table id=tablepress-1 – Requested unknown parameter ‘3’ for
   row 1. For more information about this error, please see [http://datatables.net/tn/4](http://datatables.net/tn/4)

 * Hi,
 * thanks for your post, and sorry for the trouble.
 * There are two issues happening here: The red rows mean that those rows are hidden
   from the user. To show them again, just click the checkboxes on the left of the
   rows and use the “Selected rows: Show” button.
 * The second issue is the result of a conflict with the DataTables JS library. 
   It’s caused by the table containing `#rowspan#` in some cells. Unfortunately,
   tables with combined cells are not compatible with the extra JS features.
    You
   will therefore have to decide: Either remove all `#rowspan#` and `#colspan#` 
   from the cell, or turn off the DataTables JS library by unchecking the “Use DataTables”
   checkbox.
 * Regards,
    Tobias
