Warning: register_shutdown_function() [function.register-shutdown-function]: Invalid shutdown callback 'plgSystemOpc::fatal_error' passed in ........../plugins/system/opc/opc.php on line 34
hello, i apologize for this warning, i didn't realize that it causes this message on php5.3 as it seems not to follow documentation in this matter. i also fixed second issue when clicking " click here to configure " shown by opc and which caused a php crash without any trace in any logs.
pls update with version 261 which fixes these two issues.
