has anyone encountered difficulties with the detection of the flashplayer plug-in by opera (Opera/9.80 (X11; Linux x86_64) Presto/2.12.388 Version/12.16) on linux (3.8.0-19-generic #30-Ubuntu SMP Wed May 1 16:35:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux)?
The plug-in (11.2.202.359) is located in the folders indicated in settings (/usr/lib/flashplugin-installer/libflashplayer.so,/usr/lib/opera/plugins/libflashplayer.so,/usr/lib64/flash-plugin/libflashplayer.so)

It works with firefox but is not recognised in Opera.

many thanks in advance
