The first time I visit my Home page, the text is pale grey, which is really hard to read on a white background. On subsequent visits, the text is the correct dark grey. I see nothing in the HTML to control the text colour, so I assume that's in a CSS file somewhere.
Also only on the first visit, there's an 'Uncategorized' link at the bottom of the page. Clicking this takes me to a page with a breadcrumb line Home >Archive for Uncategorized, which is formatted like a blog with Recent Posts, Recent Comments, etc, on the right-hand sidebar.
The website is hosted on someone else's server and I only have editorial control of the content, not admin privileges that would allow me to access the theme, which is Shell.
Any ideas as to what's causing this behaviour and what I can do to fix it?
