Hello, I am totally new to WordPress and a friend intitally installed it and set up a network of sites for me.
All my individual sites work fine - i am running 4.
However when i go to My Sites > Network Admin - this returns a 500 error.
The website encountered an error while retrieving http://ignitecreative.tv/wp-admin/network/. It may be down for maintenance or configured incorrectly
I get the same error for My Sites > Network Admin > Dashboard and > Users and > Sites.
What I have tried:-
re installing WordPress over the old WordPress files (i backed up my cpanel and my Word Press sites first)
deactivating all plugins (they are currently all deactivated)
increasing the memory in the config.php
making sure this line was in the wp-config
contacting my server provider who told me to do the above
finally i looked at the error log and found this..
[29-Jul-2013 23:43:27 UTC] PHP Fatal error: Call to undefined function twentytwelve_content_nav() in /home/ignitecr/public_html/wp-content/themes/ajeeban/category.php on line 40
on that line i found this
twentytwelve_content_nav( 'nav-below' );
i feel like i am close but unsure as what to do now.
thank you :)
