hy, haveing some issue. When i post something it shows up on newsfeed, but after i go to another page and back to main this post dissapear, after i reload the page that post shows up again. But its not allways, sometimes it shows posts..

Also example i write a post and delete it, but it doesnt dissapear. Just after i reload the page it dissapears.

DOnt know thats the problem. I have some issue now with optimizacion plugins..not sure if its the plugin problem.

Also i have 'internet connection error (500)'. My server admins told me it iss the problem with "/ow_pluginfiles/base/lang_1.php"

waiting any help, thanks.
