    Hi,

    thanks for your post, and sorry for the trouble.

    The cause for this is that you have enabled the features of the DataTables JS library, for a table that uses #colspan# to combine/merge table cells. Unfortunately, this is not compatible.

    Depending on what’s more important for you, you’ll now have to uncheck the “Use DataTables” checkbox on the “Edit” screen of the table, or remove all #colspan# and #rowspan# from the table.

    Regards,
    Tobias

    Hey Tobias!

    thnx for answering. So did I understand you right that this is a problem with WP 5.5 and the jquery issue?

    Hi,

    no, not at all! That’s a completely different and unrelated issue!

    In your case, you can not use the DataTables JS library’s functions, because your table uses #colspan# to merge cells. You will have to turn DataTables off for this table or remove all #colspan#.
