Hello. I'm having some problems with AdSense ads on a few of my pages. i.e. here: http://hazletonarea.net/hazleton_pa/forum/ (NOTE: sometimes the ads display correctly and other times I get question marks in place of actual ad text)
I've contacted AdSense and they seem to think the problem has to do with character encoding. Their response to me was:
"According to our parsing logs, it appears that your HTML may be encoded incorrectly. Specifically, it seems that you are using multi-byte character encoding, which is not a valid method of encoding HTML pages." ... "I recommend you look at your webserver settings or talk to your webserver administrator to make sure that your pages are being returned in a standard encoding."
I'm not super-familiar with character encoding or how to troubleshoot/diagnose this problem.
Can anyone give any tips or help?
