Under PHP7.4 it works fine. Changing to PHP8 gives the following errors:
Notice: /home/kszparpt/public_html/components/com_reportico/swpanel.php Line 1134 - file(): Read of 8192 bytes failed with errno=21 Is a directory
/home/kszparpt/public_html/components/com_reportico/swpanel.php Line 1143 - reportico_xml_reader::start_element(): Argument #3 ($attributes) must be passed by reference, value given
My Joomla modules are 4.6.1, but I note that the component installation is still 4.2 from September 2014. Should there be an updated component version?
FYI, going to this page - http://reportico.org/site/index.php/reportico-joomla-module-overview - shows 2 couple of big PHP errors.
