Personal, Thoughts

Good bye CentOS! Hello Ubuntu

CentOS, Linux, PHP, Reviews, Tips and Tricks, Ubuntu
Its been about almost more then two years since I have been playing with CentOS on many different platforms etc. Its very stable but on the other hand, PHP/MySQL updates are very hard to get and still PHP is 5.1.6.

How to solve ‘You do not have sufficient permissions to access this page.’ in WordPress

How to, Tutorials
I have been getting the following error because I changed the database table prefix You do not have sufficient permissions to access this page. The cause of the problem is that you have changed the database prefixes but still, some of the word press config is tied down to the previous prefix (wp_ or something) Just execute the following two queries [code lang="sql" toolbar="false"] -- Replace 'prefix_' with your actual prefix UPDATE `prefix_usermeta` SET `meta_key` = REPLACE( `meta_key` , 'wp_', 'prefix_' ); -- Replace 'prefix_' with your actual prefix UPDATE `prefix_options` SET `option_name` = 'prefix_user_roles' WHERE `option_name` ='wp_user_roles' AND `blog_id` =0;[/code]
