I heard i could add the banner ad (like adsense) in a new menu, so that is what i tryed to do on my site, and got that error. I read through some of the topics here, and thing about htaccess etc.
"version > admin> last item on bar> phpinfo > look at left column."
I'm not to sure where to find this, im not a huge code expert, do u mean phpinfo in FTP or admin area?
edit: the version im using is v2, which i saw in index.php, and php higher than 5.3, my host is 5.6 and higher, so that can't be the problem.
edit 2: i found the page you where refering to inside admin area, so what can i do now?
