Dompdf export error

Fatal error: Allowed memory size of 100663296 bytes exhausted (tried to allocate 147456 bytes) in /var/www/web489/html/verwaltung/vendor/dompdf/dompdf/src/Cellmap.php on line 533.

This error occures when creating a big list of data as pdf with dompdf. Is it a case of dompdf or the general php setting that needs to be changed?

Try to change the memory_limit parameter inside your php.ini file. If you don’t know where to find that file, you may add this

<?php phpinfo(); ?>

to your code - the information should be included in the output.
