I believe it's when you do not give an image URL in the summary report maker, that it throws an error:
I tried with 2 tables - both gave errors. I tried with image URLS (header and footer) and it worked.Fatal error: Uncaught Error: Call to undefined method summary_reports::field() in /home/www/testbereich/ecomo/plugins/summary_reports/summary_reports.php:54 Stack trace: #0 /home/www/testbereich/ecomo/plugins/summary_reports/generate.php(338): summary_reports->lookup_field_index('ecomo_Eigentuem...', 'ID_Eigentuemer') #1 {main} thrown in /home/www/testbereich/ecomo/plugins/summary_reports/summary_reports.php on line 54
It should be Summary Maker 2 ... bought in May 2019.... where can one find the version number?
