@v-wolf I think this is a dompdf specific issue and you have to watch the issues there. Anyway, can you send the code that is producing this error?

@niklasravnsborg I have one more time check my CSS and remove {position: absolute;} and this work now fine. Thanks )))

The problem here is in E_WARNING exception in PHP 7:
https://stackoverflow.com/a/42044413

I solved this problem just by replacing line 89:
$errorlevel = error_reporting($errorlevel & ~E_NOTICE);
with:
$errorlevel = error_reporting($errorlevel & ~(E_NOTICE|E_WARNING));
