回答1:

dompdf folder>dompdf_config.custom.inc.php file>try uncomment the line

define("DOMPDF_ENABLE_HTML5PARSER", true);

Also replace unsupported html5 tags & attributes with supported one,clear html errors for better result

回答2:

go to configuration file dompdf_config.custom.inc.php and uncomment define("DOMPDF_ENABLE_HTML5PARSER", true); and check, basically it requires html5 parser enabled in your configuration file.

I don't know why the answer regarding ("DOMPDF_ENABLE_HTML5PARSER", true) was voted down either. Because I spent over 30 hours trying to figure out why this was happening in my website, until I came across this solution. So I enabled the "DOMPDF_ENABLE_HTML5PARSER" by setting it to "TRUE" as noted above. And immediately the error regarding "No block-level parent found" was resolved and my scripts worked. Maybe the 2nd answer was voted down because it duplicated a previous answer (but cut a guy a break, why don't you? Maybe he didn't see it..). Or maybe the "downvoter" has an attitude problem.

Just uncomment define("DOMPDF_ENABLE_HTML5PARSER", true); this line from dompdf_config.custom.inc.php this file.

You can find this file for codeigniter in vendor/dompdf/dompdf this directory.
