    Can anyone here help me? I updated my theme, after that in front of my table press tables the following warning appears: Warning: Division by zero in /customers/2/3/d/ihlonline.de/httpd.www/wp-content/plugins/tablepress/libraries/evalmath.class.php on line 576

    He shows me that warning about 50 times before my page code starts (just if I visit the page in admin mode). Checkes the named php file (lines 573 – 576)

    if ( 0 === $op2 ) {
							return $this->raise_error( 'division_by_zero' );
						}
						$stack->push( $op1 / $op2 );

    Can anybody help? I know this is not a major TablePress issue, but maybe someone in here struggled with that kind of Problem. Sorry Tobias…

    Hi,

    thanks for your post, and sorry for the trouble.

    I’m a little bit confused as to why you are seeing errors like this at all. Error messages should be hidden by default, unless you have the WP_DEBUG constant set to true.

    Now, the actual cause here however seems to be that you seem to have formulas in your table where a division by 0 occurs. Can you maybe check that?

    To get a better error message (in the table cell and not before the table), please try changing line 573 from

    if ( 0 === $op2 ) {

    to

    if ( 0 == $op2 ) {

    Regards,
    Tobias

    I changed it the way you described and know the error warning ist gone. It doesnt appear in the cell, i doesnt appear in front of my table.

    One sign can change everything.

    Thx and best regards.

    Hi,

    great to hear that this worked!
    Just to give me some more information: Are you using formulas in the cell where this happened? Are you using division / in those formulas? I’m just trying to find out what exactly could have caused this error…

    Yes, I use division in some cells. But in no case I divide through zero (what would make no sense anyway).

    It appeared after I updated my wordpress theme. Must be related to that change in some way. If you need any further information do not hesitate to ask, I give you all data you need to figure out where it comes from.

    Hi,

    ok, thanks for the information!
    Can you maybe email me a JSON export of the table where you do the division? Thanks!
    (My email is in the main plugin file “tablepress.php”.)

    Regards,
    Tobias
