I had a version 1.2.3 and I tried to upgrade to V1.3.1
On com_comprofiler.zip installation in backend, it went ok through first step, then on second step stopped on white page.
Activating error log, I trapped the message :
Fatal error: Cannot redeclare _PEAR_call_destructors() (previously declared in C:\wamp\www\sitejoomla\libraries\pear\PEAR.php:773) in C:\wamp\www\sitejoomla\administrator\components\com_comprofiler\library\pear\pear.php on line 811
Seems to be a conflict between these 2 declarations:
