Even trying to rename/move third_party folder including disabling extensions in ee config file, i still get a WSOD once logging in. Once i enabled debugging to output to a file suggested by a tutorial, the error below is logged.
PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0
I don’t know if this of any relevance but this issue started after upgrading mysql from 5.1 to 5.6. Following the upgrade, i was able to still login into my admincp. But now it is not possible.
