strange that even ezpublish-errorlog does not contain any information about that error. so we are a bit struggled here.
a few questions:
a) can you activate other extensions or does it throws errors too
b) has your webserver-user proper permissions to write and create files in the settings/override and/or settings/siteaccess/xxx folders and files c) also make sure the files in var/autoloads/* are writeable by the webserver-user
if everything fails, try to activated the extension manually by editing the proper files (site.ini.append.php in settings/override as example) and then run 'php bin/php/ezpgenerateautoloads.php' in the shell (i assume you are using linux as server).
btw: what extension are you trying to install? perhaps there is a known issue somewhere.
lets hear how things are going and don't hesitate to check back ...
hi
you will find the real error in the php error log
or just enable php to display error:
at the top of the index.php add
error_reporting(E_ALL); ini_set("display_errors", 1);
Most likely it is eZ Components related issue as extension activation mechanism require it. However you have to first change error reporting as suggested above to get more details.
