Recently the flash player got updated to version 9.0r115 in Ubuntu. I already had the debug version of 9.0r115 setup thanks to installing Flex Builder for Linux alpha so I didn't actually need it but downloaded it anyway. This broke flash for Opera since 9.25 doesn't work with the newest flash player( 9.50 beta does but I prefer to work with a stable version on this computer ).
For those of you wondering about the workaround/fix, here it is:
Download the 9.0r48 flash player from Adobe's self service page.
Just make sure to use the full path for the 9.0r115 plugin(s) you have available.
