I just upgraded to PHP 7.4 and I have the same problem reported in this topic “Ver 1.5.10 and PHP 7.4”. However I have the latest version of Invoiceplan 1.5.11 which is said to be compatible normally with this version of PHP. Other information, this does not do for all tabs. I have this problem when I select the dashboard, payments, products and system settings while for quotes, invoices and customers I do not have this problem.
Any idea of this problem?
Maybe this comes from the preactivate options of PHP 7.4 version? view the photo.
Thank you for your response
