Many of you that have great websites, and offset your time and costs with some revenue from Ads, will appreciate the ability to input advertising straight from WordPress. Sometimes those plugins go a bit haywire and you need to fine-tune a setting or remove the offending WordPress plugins. One of the best plugins to do this is from Google themselves, with the Google AdSense Plugin.

I loved this plugin but lately, it has been doing some strange things like ads overlapping text or content and not being able to save the changes made. Some of it is due to the Templates used, and others due to incompatible plugins, conflicting with Google Ad-sense.

Wordfence Security

Word-fence Security for me was the culprit, for causing Google Adsense Plugin Failed Error Code 403 to not save. Why this is the case I’m not sure. Once activated, it will display ads fine, so I’m sure this bug will be fixed in the future. A quick Bing and Google search showed a heap of issues but no real solutions. I suspect Word Fence Security is being over-cautious with allowing a 3rd party to make changes.

Word Fence Security has made my Top list of WordPress Plugins list and it has locked down many rogue IP addresses that have tried to do random login attempts. Get it now.
