Hello again Philipp.

Sorry for late response. 

Unfortunately we weren't in when you submitted the ticket, and due to the national holiday, no one was able to reply until now.

Issues like this occur when something in the source file has been changed. I see all the tables were used by linking to an existing Google Spreadsheet.

Please note: Once you create a table from a Google Spreadsheet, changes in the core file from which a table is created, like:

• Changing the column’s name,
• Changing the column’s order,
• Deleting the column, and
• Adding a new column.

are highly not recommended, because the old table will not work, at the moment. If you make any of these changes, please recreate the table again.

If any of those things were changed in the source files, they caused this issue.

Can you try creating a new table using one of the links for the Google Spreadsheet?

Best regards.

Hey Philipp.

I honestly don't know what's going on on your end. Please take a look at the new table I created from one of the test documents (TEST SUPPORT table). Everything works fine.

Can you please provide me one of the Google Spreadsheet document's link, so that I can try adding it?

Best regards.

Hey Philipp.

Yeah, I believe that may be the issue here.

From our documentation:

When using Google Spreadsheets as the data source please note 2 things:
1. The data is read from the data source every time the page loads, so when your tables are large (more than 2000-3000 cells) this source won’t be the right choice since the page with large tables will load slow, or even crash after reaching a certain size.
2. There is a cache on the Google side, so when you update the table it might take up to 5-15 minutes to be reflected in wpDataTable.

Looking back on item 1. - your table has 56 columns and 456 rows, so = 25536 cells.

You can import that spreadsheet using the third option when creating a table. In that case, the table is considered to be "Manual", so it's Server-side by default, and you shouldn't face this issue. Also, that table can be edited from wpDataTables, but the changes won't affect the source Google Spreadsheet file.

Best regards.
