I have all the links and titles on the sidebar of my blog in a dark-brown colour, but during the night these appear to have changed and are now invisible. I have tried to change this back but have had no success. In addition the page titles/links (in this case ‘Home’, ‘About’ and ‘Resources’ which were a sold brown now appear white, only turning brown when you scroll over them. I am not sure how this happened as I did not make any alterations to my theme colour schemes or layout. I would appreciate advice on how to restore them.
