Hi,
When I try to update OMP 1.1.1.1 to 1.2.0, when I execute the command "php tools/upgrade.php upgrade" I get the following error message:
PHP Fatal error: Call to undefined method PKPUsageEventPlugin::PKPUsageEventPlugin() in /home/sp-dgroup/a1/www.um.es/vh/libros.um.es/omp_v1.1/plugins/generic/usageEvent/UsageEventPlugin.inc.php on line 23
It can be fixed?
Thanks,
Cheers,
Vicente
