Hello everybody .
I was searching for that bug on this forum, and I found the same bug but in older version of Piwik, (http://piwigo.org/forum/viewtopic.php?id=17045)
I did that personal plugin, but nothing has changed - still i have no photos in Google Chrome (17.0.963.56 m) - Windows XP.
There's no problem in Firefox, Opera and Internet Explorer.
PHP: 5.2.17 [2012-02-25 07:52:57]
mysql: 5.1.57-rel12.8-log [2012-02-25 07:52:57]
Biblioteki Graficzne: GD bundled (2.0.34 compatible)
have you activar personal plugin ?
Yes, it is activated...
Can this bug be caused by some changes in server configuration?
It is not a VPS but shared hosting, and there were some changes in server configuration recently (for example - reduction of possible connections to one email account per minute)
