Hi Shane and t31os_ !
Thanks for the reply and suggestions you’ve sent to help me 🙂
However, the problem of the strange message seems to be happening not because of the theme (I use Atahualpa), the upgrade of wordpress or using/not using adblock plus for Firefox.
In my opinion, if this problem is not related to the free webhosting, it is related to wordpress 2.9, because I hadn’t had similar problems in version 2.7.2 before I upgraded to 2.9. In this case, I will “downgrade” my wordpress or wait until the next stable version…
Another example of this problem: when I write a post and want to add a tag, if I click on “select among the most used tags” a new strange message will appear:
http://achmedia.com/do/adjs.php?n=092850575&clientid=45&exclude=,’> http://achmedia.com/do/adjs.php?n=001475163&clientid=44&exclude=,’>
It is similar to the first I wrote in my question !
Do you have new ideas to bring “peace and love” between me and my blog and solve this problem ?
Thanks again !
Sincerely,
Vitor Luiz
