I can't figure it out. I was goofing with various browser settings for the WAP site and now I get Error 500 and can't get back into the WAP options to turn xhtml back on. I've cleared the cache and cookies and I even tried from the device simulator. Same results.

The detailed error message is
"internal compiler error application/vnd.wap.wmlc"

Anyone got any ideas?

8830 running 4.2.2.123

I figured it out, mostly...

I had to set the browser to html only, clear the cache and cookies and log back in again. That allowed me to get back to WAP Options where I did an update to XHTML-MP. HOWEVER, if I set the browser back to wml+html then go back to WAP Options and change to WML, I can't get back into WAP Options again. I have to repeat the sequence to get back to XHTML-MP.
