Just a quick post to solve the WordPress Adsense Deluxe plugin error - "You do not have sufficient permissions to access this page".
Pretty sure I'm not the only user of this plugin so I believe some folks out there are also facing the same issue. If for some unknown force they stumble on this page, I hope that this post will help them.
Here's how to get rid of the "You do not have sufficient permission to access this page" Adsense DeLuxe problem.
Step 1. Deactivate Adsense-Deluxe plugin.
Step 2. Edit the Adsense-Deluxe (Click "edit")
Step 3. Find the admin_head and change it to admin_menu
Step 4. Click "Update File" and then go to plugin to activate the Adsense Deluxe.
If after following the steps above you can't still edit your old adsense deluxe code, make sure that you move the adsense-deluxe.php from the sub-directory adsense-deluxe_wp_plugin_v0.8 to the plugins directory. Then delete the adsense-deluxe_wp_plugin_v0.8 directory and all of the contents. ( Thanks Carlo - detailed explanation for removing the old folder can be found here)
That's all. I thank you!
