I've seen various errors on initial load of a development site I have been working on.
The most common error is an XML error that causes the page to not load the first time, a refresh resolves the error.
"XML Parsing Error: not well-formed
Line Number 148, Column 1076:"
The second error which I notice in Safari is:
"This page contains the following errors:
error on line 148 at column 2366: EntityRef: expecting ';'
Below is a rendering of the page up to the first error."
Again a refresh fixes this issue.
I have just discovered that removing the cookies associated with this page brings the error back. Is there a way I can solve this issue?
In fact I narrowed it down to the PHPSESSID cookie.
