Thanks but now it's late. My site did not work 5-15 days since I updated to version 3.64, and I have enough. I put the sh404sef and i write here
extensions.joomla.org/index.php?option=c...ink&link_id=1063

I reinstalled version 3:53 works fine. I upgraded to version 3.64 and does not work.
Sorry, but you see my problem?

Hello I installed the new version of Open Source MSC and immediately did not work with JoomSEF on and with parameter Not using SEF.
After I turn off JoomSEF and everything works!
How do I fix?

Hi. I am writing again because I have not solved the problem, but I found the others.
1. I can not delete the album creation, photo.
2. I can not upload files via plugins jomsocial JS Filesharing
Please help mi resolve the situation.

Hi. I bought jomsocial plugin, it works fine, but there something wrong. When you send private messages all ok, but when you receive, you can not see them. The component is said that first you need to authenticate. When I go to Default Joomla! router everything works properly. Please tell me what should I do to solve this problem? Thanks
