pdf print error in timeline

pdf export combines all options into the first option from the list.
Is there any solution for this?

Be sure to use scheduler 3.0 and latest backend code

Result similar to above screens can be expected if you are using old version of code.

Currently I use WP plugin v2.3.1 but I got the same results after uploading new backend code files of scheduler v3.0.

Are you using dhtmlxscheduler_pdf.js and php files from latest export package
dhtmlx.com/x/download/regula … 100909.zip


When I use the files you suggest, I got the message: " Invalid argument supplied for foreach() "
