hello all!

so, I have the latest joomla...

I just downloaded and installed K2 and in the components menu there's an entry 'com-k2' and when i click int i just get a blank page, the whole page i mean.

does the fact that i have flexicontent installed have anything to do with it? or jchoptimizer, or gzip compression..... ?

usually a blank page means an error. Try turning on error reporting to get a message that will tell you what the confilct or error is.
Many times you can disable plugins one at a time until the page loads and figure it out that way as well

I have same problem ... here is the message :

This means that for some reason the K2 system plugin is not installed/enabled. Rename administrator/modules/mod_k2_stats/mod_k2_stats.php to administrator/modules/_mod_k2_stats/mod_k2_stats.php to disable temporarily the K2 statistics module. Then install K2 again. Make sure that you are installing the latest version of K2 and that your Joomla! version is up to date. Finally check that the "System - K2" plugin is enabled and rename again the statistics module to it's original name.
