Problem Saving failed: AJAX call failed: error – Internal Server Error. Try agai

Dear Tobais,

we are having problem with table press.
if we are in wordpress dashboard and make the changes and we want to save the we are receiving an error Saving failed: AJAX call failed: error – Internal Server Error. Try again while holding down the “Shift” key.
if we do the shift key we receive a blank page.

and if we go online we don’t see that the change have been made.
If we are logged in we see the change.

hopefully you can help us in this case.

thanks Karin
