XML Invalid - Error!

[spa]

Hello,

I have a problem with - I guess - XML. I checked with php -m that SimpleXML is running. As soon as I edit a page with HTML tags, I can't save that page an these "XML Invalid - Error!" appear.

Can anybody help?

Thanks!

Stefan

Edit: I can't even open */admin - it redirects directly to */admin/pages.php and this is an empty page

Sound like you need to turn debug mode on, and check for errors.
Also health check
and error.log
