found the error.
It was in another plugin that applies to single.php of my theme. After deactivating the plugin, everything is working fine on my post page too.
Thanks for your help man !!!
I removed every single error but anything seems to work on the post page yet.
The home page and the other pages are still working fine but single post page is still not displaying the ticker and other features.
Additionally, i am having a fatal error on the post page after removing those errors.
The error is – Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 81 bytes) in /home/x7bullet/public_html/beta/wp-includes/cache.php on line 570
