Bug problems can not run on My Site

[alanwaston]

Hello everyone!
Suddenly I have started getting below error from our web site:
'commands out of sync, you can't run this command now'
This error is generated sometimes when opening a page ,and immediately after refreshing the page, error gone.

Could anyone please help me to troubleshoot this issue, so that above error message disappears permanently? Is it a database issue or application side issue?
Thank's a lot!
