This is becoming a critical issue for me as I am running an event where people are going to expect a certificate, which I won't be able to provide as I am forced to move PHP version to PHP 7.2 or higher.
I'm having trouble producing certificates for delegates to a live event. As you know PHP 7.1 is about to cease to be supported, so I need to be able to use PHP 7.2. However, when I switch to PHP 7.2 I get the following error:
Deprecated: The each() function is deprecated. This message will be suppressed on further calls in /snip/snip/snip/htdocs/dspl/administrator/components/com_matukio/include/tcpdf/tcpdf.php on line 16548
TCPDF ERROR: Some data has already been output, can't send PDF file
I have set the server configuration error reporting to NONE, and still get the error above.
