im so tired about this,please let me know i must ?

If your problem just started, then something must have changed right before this happened. So, were you doing anything on your board right before it was 'broken'?

Have you checked your error_logs to see if the error is spelled out in there?

i not found the error logs in my template lyn

If it does work normal on a default style, but not on your own style, then it is easy to conclude that the problem is in a changed template(s).

Create a copy (download/upload) of your custom style, set your account to use this test style, and start by reverting the templates oin this test style until the problems is solved. Now you should be able to determine which template(s) is causing the problem, and you should be able to solve it in the real style.

Great idea Marco. :) Thanks for the help, I couldn't think of anything else to do except trial and error methods.

Revert your headinclude, header, showthread, postbit templates
