Screen become blank after inserting the first line of the expanse report. After refresh the browser added line is visible in the expanse report. Same issue happening each time adding expanse line. This issue was observed after up gradation from 21.0.1 to 21.0.2… (Yesterday)
Check your Dolibarr log. Also, you can check your PHP error log. Maybe you can find some clue their what is happening with your installation.
Thanks
