Fatal Error BrowserName.php


Went to move my Piwik install from directory to subdomain but keep running into an error either by just moving the files or starting a new config:

Fatal error: Cannot redeclare class Piwik\Plugins\DevicesDetection\Columns\BrowserName in /home/coolestg/public_html/piwik/plugins/DevicesDetection/Columns/BrowserName.php on line 45


try to delete all files (except config/config.ini.php) and re-upload a clean version of piwik 2.5.0 in the new location. maybe it works?

I started a new config, got the same error but then went to login URL and was ok (temp error?)

rename the tmp folder and retry the folder will be created automatically.
