Okay…I’m starting to think this isn’t a problem with my blog and is instead a virus (or similar) connected to Firefox. I’ve now seen the same ads on other websites, and it doesn’t show up on my blog when I try it in Chrome.
So, this isn’t a WordPress problem. But, if I find a solution, I’ll let you know anyway.
I am having this problem on my Joomla site. I believe it was an sql injection attack. I have gzipped my remote contents and am downloading now. After I analyze and fix the problem, I’ll post a fix for wordpress.
@jlixerkun, It’s not naive at all. Now that we’ve established this problem to be caused by a malicious Chrome extension, your css rules will hide these ads from visitors who unknowingly have the “Fast Save” extension installed. 😀
I just noticed it today on my site so disabled fastsave which solves it for me on Chrome. Will wait for some update from WP which fixes this without having to hack my theme. Thanks everybody for working on this.
If this is indeed a virus, lets all list our OS and browser/version because I think it has just happend to me on a Cargo Collective site which does not use wordpress.
Mac OSX 10.7.3
Google Chrome 20.0.1132.57
Ok it’s not a virus, it’s not an sql injection the fact it disappeared after a reset means it is client side. To set the conversation straight it is a plugin/addon depending on what browser your on. If you on firefox remove the quick save addon if you on chrome get rid of the quick save extension.
